I am running Ubuntu 16.04 LTS and it was working fine. There was not any issue with the display. But today morning when I turned on the laptop from sleep, it has started to display a white grainy background around the dialog boxes and the corner buttons (close, minimise, and maximise buttons) are not visible. I can see some sort of change in the grain pattern in the position of the buttons when I place the mouse over the buttons. The buttons are working though.    The display around it is fine, as you can see.

After some gorgeous updates I witness this:

The latest updates (4/1/2018) make my laptop constantly crash the GUI/Unity:  (Intel Pentium su4100 processor)  syslog:  Jan  5 11:38:53 1810 kernel: [ 1850.327738] compiz[11911]: segfault at 0 ip 00007f6c7baf0c16 sp 00007ffd5ec71c60 error 4 in i965_dri.so[7f6c7b513000+82d000]   After login I end up with an empty desktop, just a wallpaper, GUI/Unity are in a crash loop:   No panel.  No dash.  Can't start a program. Launcher disappears. Sidebar disappears. System crash. Windows key not working. The key combination Alt+Tab not working.   Simply, the computer is not usable. Same for guest login. The only thing working: open up a terminal CTRL+ALT+T to examine log files.  I somehow forced  to let me log in and file the bug, but still lots of problems:   Dash not working Alt+Tab not working Sometimes windows all disappear for a few seconds     Any ideas for a solution or workaround?   UPDATE     If you have the same/ very similar problems, follow the link to my    report and mark there that you're affected too. Or file your own. Please leave a comment   if you wish, or upvote - this is a nasty problem - but an answer should   offer a fix or a workaround so users can use their computer again.    Without , Ubuntu can't fix issues.

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 upgraded from Ubuntu 19.10 to 20.04, and now I have a problem with my graphics rendering (strange squares on background and font problems). I use the i915 driver. Graphics card: Skylake GT2 HD Graphics 520. I tried to reinstall GNOME shell and Xorg server. Nothing helped. Also Chrome browser breaks on most of pages.

When I move my mouse, the window in Blender blurs / smears down. Why is this is happening?

My laptop boots up as normal,but using for like 10-15 minutes, screen goes black and there is red vertical line on the right side of the screen. The only thing you can do is restart it and use it again.

This happens apparently because of scrolling and because the windows is wider than the whole content.  So, often the last button(s) (like Skip) not seen and unaccessible.

I know that it's just a tiny graphic problem but do you also get a white line (or extra padding) after the last entry in the context menu?

I have recently installed Ubuntu Gnome which has the latest version of Gnome 3 running on it, and I have noticed that on windows there are no minimize buttons, and no maximize buttons, although I can see that you do get the options if you do a right-click. I have already read  question, and its answers, and have found that still none of them answer my question.  So my question is, as made clear in the title, how can I bring back the minimize and maximize buttons? Is this a bug? Or have Gnome decided not to have them?

My laptop keeps on having weird screen glitches, sometimes for a second, and that goes away just by moving the cursor, sometimes, making me restart the whole thing.  I could still use the play/pause key and it still played/paused the video that was running even though the screen was completely teared.  Also, printscreens actually print a normal screen and do not show the problem.  Some pictures of the screen when it happens :     Do you guys know what I could do to solve the issue ?

Windows 7 has a new "Show Desktop" button all the way at the edge of the system tray area. Is there any way to get rid of it?  I never use it because I just press Win+D instead, and it's kind of annoying to me.

I can't work out why Altium is doing this, or how to undo it, or how to make it stop doing it.  It happens when I use the 'Find Similar Objects... ' option; all of objects that it hasn't found are faded out and I can no longer select them.  Anyone know how to fix this?  Additionally, if anyone knows how to change, en masse, the components' footprint library to 'Any' through the SCH inspector, that'd be really helpful too.

I just installed Ubuntu 17.10 today, and noticed that a lot of desktop environment has now changed from Ubuntu 17.04.  I'm just wondering if there is a way to change the the setting of those desktop effect for example, Change the speed of the app drawer to appear when you click it.

If I press the "include alpha-button" in the Mix-Color-Node, I get white borders. Otherwise i've got a perfect alpha but no blue background.

I can't figure out how to get rid of this red dotted line in the middle of the viewport.

I installed ubuntu 16.04 LTS a week after official release using the mini ISO, then ubuntu-desktop without recommended packages. Since then, just installing packages on a need to basis.   After trying to wake the computer from sleep by using the touchpad, the light on the power button stops blinking and I hear the sound of the hard drive coming online. But :    the screen stays completely off, no backlight. the laptop doesn't respond to any keyboard presses. Everytime I use The magic SysRq to restart the laptop. Long pressing the power button works too.   This problem wasn't present when using ubuntu 14.04 LTS  The proposed solutions in all the possible duplicates on this website didn't solve my problem. One big difference is that my laptop screen is off not just blank.  Possible helpful informations. All got after system reboot.
