If I move the mouse or use the keyboard to do anything that would require redrawing the screen, it flickers, and then often goes black for a second or so.

I did not have this problem on 15.10 on the same machine. I have the same problem when booting into the 16.04 live CD.

I have 14.04.5/16.04 or newer and an AMD GPU. I'm not getting the performance I want, and some programs say they need things like OpenCL.  I've heard about fglrx, but if I try to install it on my machine, it breaks and I have no GUI.  Is there anything I can do to get my AMD card working to its full potential?

I have an Asus UL30JT. It has Nvidia Optimus technology which I am not really interested in. I currently rarely use this laptop with it being connected to power. And I want to be able to play video at high res, play games and do some OpenCL coding.  In the BIOS I switched it to NVIDIA only (non windows 7). Previously, this worked just fine, using the nvidia driver.  After upgrading everything was broken. I have added nomodeset and blacklist.nouveau=1 as kernel options. The nvidia drivers install without error. However they are not found/used.  jockey-text -l kmod:nvidia_310_updates - nvidia_310_updates (Proprietary, Enabled, Not in use) kmod:nvidia_304_updates - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_313_updates - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_310 - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_304 - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use)   Trying to load the module manually fails as well.  sudo modprobe nvidia FATAL: Module nvidia not found.

I have just updated (through Software Update) to Ubuntu 16.04 LTS from 15.10. There are random instances of screen flickering throughout usage. After noticing this issue, I installed Compiz Config Settings Manager, selecting Force fulls screen redraws (buffer swap) on repaint, which did nothing.   Is there any way this could be related to compiz settings or is this another issue?    EDIT: not fixed after clean install, upgrade to kernel 4.5.2, however screen flickering is reduced, it is every now and then (10 minutes apart). I will see if upgrading to kernel 4.6.0-994-generic will fix this.     EDIT: fixed as of kernel 4.6.2 generic,  currently running 4.7.2 without any issues.

Alright my computer when i play games will flicker white across the screen and some games will even crash immediately after getting in the game, I only have the problem with games that require high graphics, I notice the white flicker in games like Minecraft but its barely noticeable so its not a problem, the white flickering started randomly while I was playing.  I've switched out every part of my pc except for the motherboard and Processor. I've redownloaded windows 3 times with different CD's, I've downloaded all the drivers and tried old and new ones with many parts that I could download drivers on.

I have an older Nvidia video card and my PC crashes when installing the driver for the video card in Ubuntu 16.04. When I get to the login screen but no further: after entering my password, the system went into a loop and returned always back to the login screen [with funny stripes present].   How do I fix this problem?

To summarize the answer: switching to proprietary drivers should work, but the artifacts disappeared for me even on the free drivers now.  Update: since switching back to the proprietary AMD driver (fglrx), I haven't seen these artifacts.  Occasionally I see artifacts instead of correctly rendered characters:    For now I have only observed this in Firefox.  The characters become normal once I select the text.  What's the issue here and how can I solve it?  Graphics card:  AMD Radeon HD 7790 Driver: radeon (free) -> now I'm no fglrx and am not seeing the artifacts (see the update)

I had the beta drivers running previously and after a standard update it stopped working. What I've tried so far:  sudo apt-get remove --purge fglrx*   Then downloaded drivers from Amd website and unzipped it and ran:  sudo ./amd-driver-installer-catalyst-13-4-x86.x86_64.run --buildpkg Ubuntu/trusty sudo dpkg -i fglrx*.deb   After this the Ubuntu  guide wants to make this:  aticonfig --initial   and it returns:  Unable to open /etc/ati/control, please reinstall the driver. aticonfig: No supported adapters detected   The adapter is 280x and as said, it worked previously with the same drivers and with the same installation procedure.  Any ideas?

I know this might be a duplicate, but I've read a lot of threads about this and none pointed me to the solution.  When loading GRUB2 I have a black screen (with static white cursor on the upper left) which goes away as soon as the Ubuntu login page comes up, but stays there forever if I boot Windows (even though I can hear the 'login sounds').  I have a dual boot system with Ubuntu 14.04 and Windows 7 (both 64-bit) and I have a NVIDIA VGA. The Windows installation used to work just fine, with the VGA doing its job. My monitor was plugged on the motherboard when I fresh installed 'trusty tahr' (I have a integrated intel graphics CPU) and after that I immediately installed the video card drivers from the official repo (nvidia-331 I believe). Their installation was successful (at least from what I see from the 'Nvidia X serve settings' tool). After that, if I plug the monitor on the video card, grub goes on the black screen, but I can anyway boot Ubuntu and when the login page comes up the video output is normal. The same cannot be told when Windows boot.  I tried many suggested fixes: nouveau.modeset=0, nvidia.modeset=0, nomodeset options in the /etc/default/grub file and I also tried blacklisting the corresponding kernel modules adding a .conf file in /etc/modprobe.d. None of that solved my problem.  I insist that this must be a grub video problem, since if I plug my monitor on the mother board I can boot successfully both Ubuntu and Windows and also the boot-repair tool for Ubuntu doesn't find anything significant (see ).  I'm currently out of ideas, has anyone any suggestion? It would be much appreciated!  Lorenzo

I have a ATI Dynamic switchable graphics on a HP Pavilion g7 (hp pavilion g7-1246ef) but it has no support in Win7 32-bit.   It seems that I have 2 VGA controllers:   One on-CPU Intel for energy-efficiency One discrete card (an ATI/AMD Radeon HD 6470M in your case) for rendering.     The Intel driver provided Aero support and other options and the Windows update gives a generic driver for AMD but drivers from AMD and HP made for the switching part (including AMD Catalyst Control Center) are not working in this case. More on this (especially the comments) - .  I gave up for now but I am curious what happens meanwhile.  I know that the AMD Catalyst Control Center allows choosing manually the VGA or letting the applications choose which VGA to use. But what happens when there's no AMD Catalyst Control Center present?

I purchased a new Lenovo g580 laptop. But I am totally disappointed when I installed Ubuntu on it. Almost all drivers are not working. :-(  The laptop configuration is  intel i3 processor  Nvidia GeForce 610M graphics card.  I couldn't find the nvidia drivers in the additional drivers (jockey).  The main problem is that the brightness control not working. I tried lots of methods explained in this site, but the result again disappointed me.  I am a student and I am using Linux, and the brightness control is the most urgent problem that have to be solved.  So experts please give me a solution.  thanks in advance

I have a Samsung NP-QX411. It has two graphics cards, Intel and nVidia. The Intel drivers were quickly found and is fully functional. But nVidia, I have tried installing several drivers in different ways. But I can not run it without success. I do not understand how Ubuntu has by default the switch Hybrid Graphics option. What should I do?

This is on an Early 2011 Macbook Pro 17" with i7 2.2ghz and the Intel + Radeon HD6750:     If it is a screen error then I don't mind fixing it myself, but if the GPU is the problem, I'm worried I might have to buy a new logic board assuming I can't use the GPU.

I have been on quite the odyssey trying to get steam to work.   I am using Ubuntu 15.04 and the linux 4.0.5 kernel. System specs:  Intel haswell quad core CPU AMD Radeon 7870 Graphics Samsung 850 EVO SSD 16GB Memory  I was able to get steam to work in 14.04LTS, but I had other problems with that version; namely flash issues in chrome. So I updated to 15.04 and my system is more stable (except for steam, there is always something...)  I have tried removing various lib files to no effect. I have removed and installed steam a few times and it doesn't appear to be working.   I tried switching to the proprietary drivers, but that causes my system to hang when it boots. In order to fix it I completely removed and purged fglrx from my system. I attempted to reinstall the proprietary drivers via command line according the ubuntu page instructions, and ran into the same error, so I am stuck with the open source drivers.  I can only assume that my card is no longer supported by the proprietary drivers, which is frustrating.   Before I removed the proprietary drivers I got the same error as these guys:   Now that I have removed the proprietary drivers I am getting missing lib errors, which I guess is not surprising:  libGL error: unable to load driver: radeonsi_dri.so libGL error: driver pointer missing libGL error: failed to load driver: radeonsi libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast  I am about ready to give up and am seriously considering buying an Nvidia card. If anybody has any suggestions on what else I can do, I would really appreciate it.

I have both Ubuntu 14.04 and Xubuntu 16.04 installed on one of my older desktops.  While both work fine, I experience screen tearing while dragging windows around in Xubuntu. However, I do not experience it on Ubuntu.  It is using the motherboard's built-in AMD graphics chip.  Note: This exact situation also holds true for my main desktop with a GTX650 graphics card...    At this point, I'm thinking it has something to do with Untiy being a 3D DE, and XFCE being a 2D DE...

I am running kernel v4.13.0-36-generic on Ubuntu 17.10 on an HP Omen 15. I have a hybrid NVIDIA Optimus graphics card. I dual-boot Windows 10, which can play audio from the same external monitor over the same HDMI cable I am attempting to use in Ubuntu. I can see video on my external monitor in Ubuntu.  I have tried , but in the former no HDMI audio device appears, and in the latter all HDMI devices show up as unplugged.  I have had the most success using the proprietary nvidia-384 driver installed via the Additional Drivers tab of Software &amp; Updates. Using this driver I am able to see video on my external monitor, play audio through my laptop speakers, and boot reliably.  I have tried using nvidia-387 and nvidia-390 from  with , but I can't even boot or see video on my external monitor reliably using these drivers. I observed that /etc/bumblebee/xorg.conf.nouveau and /etc/bumblebee/xorg.conf.nvidia detected my GeForce GTX 1050 Ti as a discrete graphics card, which I believe is incorrect, but am unsure how to override these settings to indicate that my graphics card is a hybrid.    I installed , but after rebooting was stuck in a boot loop, so I ran sudo nvidia-uninstall.      I disabled Secure Boot.  I tried using kernel v4.15.4, but only found it even more difficult to boot reliably.  I tried . I do not know how to switch from hybrid to dedicated graphics mode as the author of that solution suggests though, so that may be why it didn't work for me.  $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC295 Analog [ALC295 Analog]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4]   Subdevices: 1/1   Subdevice #0: subdevice #0  $ lspci 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v6/7th Gen Core Processor Host Bridge/DRAM Registers (rev 05) 00:01.0 PCI bridge: Intel Corporation Skylake PCIe Controller (x16) (rev 05) 00:02.0 VGA compatible controller: Intel Corporation Device 591b (rev 04) 00:04.0 Signal processing controller: Intel Corporation Skylake Processor Thermal Subsystem (rev 05) 00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-H Thermal subsystem (rev 31) 00:16.0 Communication controller: Intel Corporation Sunrise Point-H CSME HECI #1 (rev 31) 00:17.0 SATA controller: Intel Corporation Sunrise Point-H SATA Controller [AHCI mode] (rev 31) 00:1c.0 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #1 (rev f1) 00:1c.4 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #5 (rev f1) 00:1c.5 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #6 (rev f1) 00:1c.6 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #7 (rev f1) 00:1f.0 ISA bridge: Intel Corporation Sunrise Point-H LPC Controller (rev 31) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-H PMC (rev 31) 00:1f.3 Audio device: Intel Corporation Device a171 (rev 31) 00:1f.4 SMBus: Intel Corporation Sunrise Point-H SMBus (rev 31) 01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev a1) 03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

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.
