Yesterday, the system asked me if I wanted to upgrade to 13.10 from 13.04. Since that was the first time for me, I decided to proceed and ran the installation without worrying about it.  After the system completed the upgrade, my PC was rebooted and the new version of Ubuntu signalled that the desktop would have run in low graphigs mode due to a graphical driver problem. I couldn't manage to fix the issue, so I continued with the low graphics mode... but nothing showed up. I wasn't even able to access one of the TTYs.  So I ended up rebooting the system and accessing the recovery mode. I uninstalled all my ATI graphics drivers along with xorg-server and fglrx. After rebooting, I was able to access the login session of Ubuntu, but after confirming my credentials, the desktop wouldn't show up, but instead a black screen appeared with the following message:  System program problem detected  I couldn't figure out the problem and tried to restore/re-install all the graphics elements I knew. but nothing worked. The screen still remains black and won't show the icons nor the Unity bar.  What would you advise me to do? Should I try launching a fresh install of the OS from the live CD?  Thank you.

I used the built-in upgrader to upgrade to 19.04 today, and I'm now stuck in a login loop. I have tried many solutions from forums, but nothing has worked. Is there something I'm missing or anything else I should try?   From what I've seen, I don't think that there is an Xauthority file on my computer. I'm on a Dell XPS 15 with a GTX 1050Ti Max-Q GPU, and a Core i7 processor. I also have a Windows dual boot, and while Ubuntu's my main OS, luckily almost everything is on GitHub, Google Drive or my Windows partition.

When my computer blanks the screen after the timeout (10 minutes) or after I turn off the monitors and turn them back on some time later, I only see a black screen with the mouse pointer. I can move the mouse pointer, but nothing else happens.  I am able to switch to the console with Ctrl + Alt + F3 and then switching back to the display with Ctrl + Alt + F1 gives me the login screen. But after logging in, I get the same problem.  Restarting gdm3 from the console does not seem to help. It gets stuck initializing and then I have to hard shutdown. The only thing that works is to restart the machine from the console, but that is annoying.  Has anyone else experienced this problem or have any ideas on how to fix this?  My machine is Ubuntu 18.04 with the 4.15.0-32-generic kernel.

I recently installed Ubuntu 14.04. Shutdown and logout from the top panel are not working.  They worked fine when installing the OS, but a few days back I installed fglrx drivers for my ATI graphics card. They didn't work and I got low resolution problems and Ubuntu didn't boot. I solved it by removing the fglrx graphic driver from the recovery mode and Ubuntu started to boot and work just fine, at least that's what I thought.  But now the shutdown and logout options in the top panel don't work. I have to logout using ctrl+alt+delete and shutdown with the shutdown option in the top panel (shutdown option works after logging out but not when logged in as a user).  I re-installed Ubuntu 14.04 LTS and shutdown options worked fine but after installing updates they stopped working again. I thought its the graphic driver fglrx installation problem but now i know its not that. I think its a problem with some file that got installed from Ubuntu updates.  Does any one know how to solve it?

I recently made the switch to Ubuntu. Everything on my laptop works fine except my hybrid graphics card. It is Intel graphics combined with Nvidia GeForce GT650M. I tried Bumblebee, but primusrun doesn't work (segmentation fault, core dumped) and optirun works with glxspheres64, but steam games look worse with optirun than with Intel graphics (e.g. Surgeon Simulator 2013 runs fine with Intel and hangs a lot with optirun)   I tried Nvidia Prime, but it gives me a black screen on startup after install, so I can't do anything and have to power off my PC with the power button. I also tried nvidia-prime 0.5 on Ubuntu 14.04, and then I get 'low-graphics mode' and I can't get to Unity.

I have a laptop with ATI Radeon 6770M HD Hybrid graphics card. In Ubuntu 12.04, I installed the fglrx driver through "additional drivers" and it worked. (I can even switch GPUs). But in the new Ubuntu 12.10, after installing, Unity won't load.   Only the mouse and the wallpaper. If I initialize the settings sudo aticonfig --initial then after rebooting it gives a warning saying I'm in low graphics mode! How to fix this?  Earlier I used software source to install the drivers. But when using the terminal, I got this warning :   update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken   Update : Filed a bug report in launchpad :

I'm having some problems getting Ubuntu to install. I'm running Windows XP Home (32bit) on an older Dell Dimension 2350 with 1GB ram, trying to install either Ubuntu 12.04 LTS (32Bit) or 13.04 (32Bit) inside VirtualBox. Both versions of Ubuntu don't make it past the purple screen with the loading dots. When I change over to the "non-graphical" version, with the scrolling text, it starts to list a series of tests that are either [ok] or [fail]. There are only a few that fail, and my search on those indicates that they're not that important. There are a few settings for this VM that I've tried tweaking based on other searches for an answer (such as Enabling IO APIC, switching the Chipset to ICH9, changing the Video Memory size, Enabling 3D Acceleration, and Enabling PAE/NX. More or less, I get to the same point.  (Once I got to the screen with Desktop in the upper left corner, and the red-ish background. But an error came up that basically said there was an error, and that I could send off a report or hit cancel. I hit cancel, and instead of the installer coming up, nothing happened)  The last check that is run is "Stopping System V runlevel compatibility [ok], and a bunch of Starting [ok]s. Then I get a black screen, then a half purple half black screen graphical error. Sorta looks like snow, I don't know how else to describe it. After a while. That goes away and is replaced by a black screen again. Nothing else happens.    I like to think I'm fairly good at solving problems and following instructions, but I don't even know how to go about diagnosing this. Most of the solutions I've seen seem to involve entering things into a command line, but doesn't the OS have to be installed to be able to do that?  This is a for fun/learning experience project, so it's nothing too pertinent. But I would like to figure this out.

I have installed Ubuntu 20 alongside Windows 10, then removed Ubuntu and grub issues were also solved, now I am unable to install Ubuntu 20 again. I am installing through USB and a black screen comes with some lines.  It is when I am booting the installer. Ubuntu is not installed on my system.

A few days ago, I accidentally replaced my desktop in Mint 18 with a virtual console with an errant keystroke. Not having an obvious way to reverse the changes, I logged in and typed exit to exit the console and go back to the desktop. Instead, the computer rebooted, and I lost God-only-knows-how-much unsaved work.  After showing the Mint logo and flashing a message underneath it far too quickly to read, the computer now boots only to a black screen. By pressing esc during reboot, I can get to a Startup Menu. I ran disk checks and memory checks using it, and they all came up clean. None of the other options in this menu help. I have no idea what to do.  The screen is clearly receiving power, and the black screen that it boots to shows a dash or underscore in the top right corner.  How do I get my computer back? It's an HP Pavilion laptop.

I have yesterday updated packages and today the system cannot boot properly. After seeing the Kubuntu logo there is a black screen which shows repeatedly.     Stopped User Manager for UID 121.

I was using 13.04 as a guest OS on my VirtualBox 14.2.18. Host is Windows 8. After upgrade to 13.10 Ubuntu does not start. I can see a black screen and blinking cursor. I am pretty new to Ubuntu. I suspect a problem with graphics drivers. I can access tty and all files (/home) are there.

I'm suffering from the dreaded . The problem is intermittent and can be "solved" by putting the computer to sleep or restarting it. I hope simply restarting the graphics drivers will remove the symptoms of the problem.  would seem to indicate that restarting the graphics drivers is possible in Windows 7. My question is: how?

I have recently upgraded Ubuntu 19.10 to latest LTS Ubuntu 20.04. After updating, I get serious artifacts on my screen. Every time I reboot (or log-in), my screen is fuzzy or scrambled (picture attached):     This is temporary. The fuzzy screen goes away when I change the background. But it reappears the moment I reboot or log back in.   I have Intel HD Graphics 520 (Skylake GT2).  The output of lspci -nn |grep -E 'VGA|Display' is:  00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake GT2 [HD Graphics 520] [8086:1916] (rev 07)   Update:   On enabling Wayland in Ubuntu 20.04 and logging in to, these artifacts are however cured.   This is okay for now, but I am not sure about Wayland as I have not yet used it before.   Is there a way to correct the graphic issue with normal Ubuntu startup?

My Ubuntu 12.04 was normally updated through the Update Manager, something about gtk. Then I rebooted and now all that shows after the splash screen is a blue screen that only shows the cursor.
