My system has integrated graphics, Intel i5 chip. After upgrading from 5.8.0.48-generic to -49, after reboot, I noted browser screen does not update correctly. Missing images and text, flickering. I opened a terminal to check the kernel version installed (uname -a) and noticed the terminal also has same problem, flickering and characters appearing and disappearing. So I booted the previous kernel, 48. and everything was fine, no problem with screen update. Today, I checked for update and there was 5.8.0-50 available part of the update. After update, booted with default (5.8.0-50-generic) and noticed the same screen issue, but not as bad as the previous kernel, -49. Any comments would be appreciated.

I'm not sure what's caused it. I haven't changed any system settings. The only thing I've done that may have broken something is updating my software. My update was: upgrade linux-generic-hwe-20.04:amd64 5.8.0.48.54~20.04.32 5.8.0.49.55~20.04.33 upgrade linux-image-generic-hwe-20.04:amd64 5.8.0.48.54~20.04.32  upgrade linux-headers-generic-hwe-20.04:amd64 5.8.0.48.54~20.04.32  upgrade linux-image-extra-virtual:amd64 5.4.0.70.73 5.4.0.71.74 upgrade linux-image-generic:amd64 5.4.0.70.73 5.4.0.71.74 upgrade linux-libc-dev:amd64 5.4.0-70.78 5.4.0-71.79 upgrade libseccomp2:amd64 2.4.3-1ubuntu3.20.04.3 2.5.1-1ubuntu1~20.04.1 upgrade nomachine:amd64 7.3.2-3 7.4.1-3```  Removing nomachine did not solve the problem. It was far worse before, I'm not sure how to describe exactly, but my entire screen's UI was glitching out. So I rebooted and that stopped, but now the terminal text looks like this:  I haven't changed any terminal settings. This seems to be occurring in the entire OS. Here is another example:  Not sure how to go about troubleshooting this? I don't have the time to reinstall the OS, nor do I think I should have to because this is just ridiculous and shouldn't happen. I'm not aware of anything I've done to make the system unstable. Edit Earlier I also tried booting the PC. It failed and got stuck on some command in a terminal (didn't manage to take a photo of what it said). So I rebooted into recovery mode with both available kernels. I was getting strange glitches like this:  That didn't work. So I rebooted the PC normally, and now I somehow logged in fine. Now I'm getting popups saying to report a system error. It says this:  Environment  Ubuntu 20.04.2 LTS GNOME 3.36.8  sudo lshw -class display   *-display        description: VGA compatible controller        product: Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller        vendor: Intel Corporation        physical id: 2        bus info: pci@0000:00:02.0        version: 06        width: 64 bits        clock: 33MHz        capabilities: msi pm vga_controller bus_master cap_list rom        configuration: driver=i915 latency=0        resources: irq:33 memory:f7800000-f7bfffff memory:e0000000-efffffff ioport:f000(size=64) memory:c0000-dffff  I also did , which passed with 0 errors.

I built a new computer and am now getting weird graphics glitches when browsing the web or streaming video in a browser.

I have tried fresh installs of the latest Ubuntu 18.04 and 20.04 versions. I have tried a couple methods of updating or changing the kernel versions. Changing resolutions, refresh rates, or scaling does not fix the issue.

I'm running Ubuntu 13.04 on DELL XPS L501 - Nvidia GeForce GT 420M. I'm using kernel 3.9.0-030900-generic.  All kernel-headers are installed in the system.  and  I've tried the following.   Use apt-get to install nvidia-current (which download 304) &amp;&amp; load using modprobe Use apt-get to install nvidia-310 &amp;&amp; load using modprobe Download nvidia 64-bit driver nvidia-319.23 for 400M series and install Use swat-x repo to install nvidia driver   All of these failed. And I tested it everytime like this   After the module is loaded (checked from lsmod),  restarted lightdm tested from get.webgl.org  (Google-Chrome webgl support is enabled)    Problem faced with nvidia-xconfig   after running nvidia-xconfig (which writes to /etc/X11/xorg.conf), and restarting lightdm, my display res changes to 640x480. and had to remove this file to revert back to old setting Have also tried commenting out those two lines which adjusts Horizontal and Vertical Setting in xorg.conf. That just rectified the resolution. But still I wasn't able to use the graphics card (webgl).   EDIT 1: (nouveau)   Tried rebooting after each installation Removed (purge) all of nouveau* before starting.  Removed one more package (dont remember the exact name though) - xorg-xserver-blah-blah.   EDIT 2: (bitlbee)   I had bitlbee installed before. Removed that too before starting installation. When bitlbee was present, NVIDIA-3.9-x86.run (downloaded from nvidia) was not able to recognize graphics card. But it did when I removed bitlbee. (So I'm assuming here that it should work if graphics driver was installed properly)   EDIT 3: (software-properties-gtk)   sudo software-properties-gtk the Additional drivers tab is always NIL. (before and after installation) (even if the installation was successful)   Have been trying this the whole day, and done it quite a few times. None of them worked.  Need help! Is it the problem with kernel-3.9, that there are no updates for this ?

Since my previous questions were not answered I will try to ask again more precisely.  I previously had the Nvidia driver installed and working correctly.  Then the ubuntu software update did something which broke it.  In fact, it completely de-configured it so that the standard display driver is used when the computer reboots.  I would like to re-enable the existing Nvidia  driver without re-installing the Nvidia driver.  How do I do that?  This machine is no longer connected to the internet.  NOTE: I am not asking how to disable automatic updates in this question.  I asked that elsewhere (and it wasn't answered).  NOTE: I am not asking how to stop the Ubuntu software updater from breaking the Nvidia driver the next time it updates the system.  That would be nice to know, but I asked that already and did not receive the correct answer either.  NOTE: Please don't make this as duplicate simply because someone else asked a question about Ubuntu and the software updater.  Try to read the actual question and see how it's different and try to realize how annoying it is when users have to spend hours of their own time to correct the problems that other people causing by incorrectly designing software updaters.

Supposing I am using Ubuntu 12.04(LTS), and it uses the 3.5.0-37 kernel.  If i wanted to use the 3.9.6 kernel, how could i use it? I dont want to upgrade to 13.04  Would I have to manually download this kernel, compile it and make its initrd, or could I fetch it using apt-get install by enabling some repository?  Please Help.

Hello I upgraded all packages on my Ubuntu, and kernel also. But in upgrading process kernel upgrade failed, and I must always after grub load select older kernel. It is a terminal command to reinstall latest kernel?

I have a MacBook Air 13 inch laptop since 2011.  Quite recently the screen had problems.  It start flickering, changing colors, and vertical lines appeared in the middle of the screen.  All these are starting when I move the screen backwards, forward or when I am lightly pressing with the fingers the top of the screen.  This is also the only way to re-adjust to normal operations. Any recommendations?

I am using the official nVidia driver because my card (GeForce 750 Ti) isn't yet supported by the Ubuntu one. Every time the kernel updates, my system breaks.  I've formatted my system two-three times because of kernel updates and today I decided to try to fix it. I tried to fix it with this method and surprisingly it works.   Switch to console (After waiting for the nVidia driver to crash, as it does when you switch consoles :p) Run a complete uninstall  sudo ./&lt;DRIVER&gt;.run -uninstall  Reboot and switch to the on-board card Update  sudo apt-get update sudo apt-get dist-upgrade  Reboot again Reinstall driver  sudo ./&lt;DRIVER&gt;.run  Reboot and switch back to the NVIDIA GPU   Is there a better/easier/faster way to update without going through all this?

NB: Nvidia has released an official fix; please see ,  and/or .  Upon waking up Ubuntu 16.04 from Suspend, the following graphical glitches appear around all windows, context menus, and similar:      This is currently known to affect the following NVIDIA cards running the proprietary drivers:  NVIDIA GeForce 610M, driver version 375.39, 340.102 NVIDIA GT 630M, driver version 375.39 NVIDIA GTX 650, driver version 375.39 NVIDIA GT 740M, driver version 378.13 NVIDIA GTX 745, unknown driver version NVIDIA GTX 850M, driver version 375.39, 378.13 NVIDIA GT 940M, driver version 375.39 NVIDIA GTX 950M, unknown driver version NVIDIA GTX 960M, driver version 378.13 NVIDIA GTX 970, driver version 375.39 NVIDIA GTX 970M, driver version 375.39 NVIDIA GTX 980 TI, unknown driver version NVIDIA GTX 1060, driver version 375.26, 375.39, 378.09 NVIDIA GTX 1070, driver version 378.09  The above above list has been sourced from reports from other users here on AU,  thread, and  thread. NB: This is be no means an exclusive list. It probably effects nearly all Nvidia cards.  Furthermore, this issue has been replicated on a clean install where the only change was a software update and the installation of the latest NVIDIA drivers.  What is going on, and how can it be resolved?

I am not looking for a workaround or a hack.  I am just confused.  14.04.1 has been released now for a week, and one of my machines which is on 12.04, and another one which is on 14.04 both don't have the upgrade options.  I see there is a 14.04.5 release on august 7th but I am not sure what a candence event is.    It is hard to believe that it is not an issue that is going to be resolved otherwise I would hope this would be posted on the Ubuntu blog.  I cant be the only one on the last LTS waiting for it to update so I can finally go to the latest kernel and properly use my core i7 graphics.

Currently I'm running Linux-3.0 and I want to update it to Linux-3.3.1 the latest stable kernel release as mentioned at . Can I update to 3.3.1 in Ubuntu without any risk of crashes? I'm updating my kernel regularly as provided by the Update Manager..Currently I have Linux-3.0.0.17..Can I update?  NOTE:  The latest kernel version any user is supposed to use in Ubuntu is updated automatically via the Update Manager, so no action is normally required by user regarding kernel upgrades. What the question author is referring to is mainline kernel, see:

I have installed  ubuntu 20.04 on my laptop specification are intel i3 6th gen with intel graphics card 520,screen resolution 1366×768. when i lock desktop to temporarily turn off the screen but when i press power button to wakeup the screen my screen flickers continuously,  this issue occurs only when locking the desktop or when screen goes off automatically. I had same issue with ubuntu 18.04 version and kali linux. But when i downgrade ubuntu to 16.04 it was running fine and same with kali linux when i installed slightly older version of kali linux it was also running fine. I am having this issue with only newer versions of ubuntu and kali linux. I have tried solution of  1)reducing screen size 2)installing older kernels  And also when i installed ubuntu 20.04 on my friends laptop it was also running fine in his laptop, specs are i5 8th gen nvidia graphics card,screen resolution 1920×1080

Tonight I upgraded to 11.04. Problems. Once I had finished the upgrade, I restarted my computer as it told me too. When I got past the ubuntu 11.04 (purple background orange dots), it simply went to the terminal and asked me to log in. I tried to restart the X server with "sudo service gdm restart" but no display popped up. I happened to have a few NVIDIA drivers in my downloads file also so I gave these a try, but the "install script" failed.   After all this I booted Ubuntu in graphic failsafe mode. I then decided to see what would happen if I removed the proprietary driver. Upon doing this and rebooting my Ubuntu booted into graphical mode "yay!". So without the Nvidia drivers I can finally see something other than terminal, but, I need those NVIDIA drivers for my work. So what can I do? I have tried installing the new NVIDIA linux drivers from the NVIDIA website, and have tried Installing the recommended driver via "additional drivers", but both have resulted in my being stuck in terminal.  If you can help or give me some advice PLEASE DO! I am really in a very bad situation...

I am using Ubntu-GNOME 16.04 with GNOME 3.20 When I install Nvidia graphic drivers by sudo apt-get install nvidia-361 , I am facing the following problems. During the installation of Nvidia-361, it asks me to select Default Display Manager with the following options  lightdm gdm3  Consequences of selecting lightdm  : The login screen becomes like this :  I don't want this screen. I want the Default (nice) GNOME login screen. Furthermore.... When I enter my password and press enter, I get this screen for about 5 seconds :  Consequences of selecting gdm3  : Well I get nothing! After rebooting, Ubuntu loads ... then all of a sudden my display turns of. No Light. I have waited enough but alas :( no change. NOTE: I have tried both nvidia-361 in default repositories and nvidia-361 from ppa:graphics-drivers/ppa. No difference. I also tried installing nvidia-364 and nvidia-367 from graphics-drivers:ppa , alas :( no much difference. Using nvidia-364 or nvidia-367 : When I tried these drivers, I could get GUI back. But I got stuck on the login page : login loop

My laptop computer has a Nvidia video card and runs Ubuntu 12.04 LTS 64-bit. During an upgrade yesterday it seemed as a new Nvidia driver version 304 (if I remember correct) was installed. After upgrade and reboot, I opened the Additional Driver tool and found that the Nvidia driver version 304 was in use. So far so good.  However, the Additional Driver tool also reported that there existed a Nvidia driver version 319 and that this driver version was recommended. I then selected to change to this recommended driver, the driver was downloaded and installed, I rebooted the system and ended up with a black screen and a command shell.  How to change proprietary Nvidia video driver using the command line and revert back to the previous version that worked on my system?  (A second question: How can it be that a video driver that apparently does not work was recommended?)

I used the upgrade manager to upgrade from 17.04 to 17.10. When I start the machine, I only get a black flickering screen now. I was using the nvidia binary drivers before the upgrade.     NOTE: This question (and answer) relate to a specific issue when upgrading from 17.04 to 17.10 while using Nvidia or AMD binary drivers. You might experience a completely different issue. For that please see the more general question .
