Public bug reported: Don't know what's happening and what is responsible. I've installed Xubuntu 14.04 32bit. I'm working on 4 desktops (2 of them have Chromium with few Thunar and gedit and the other 2 have full screen emacs) and sometime when I do something in Chronium everything disappear and some part of the screen show current desktop and some show youtube video I was watching in the morning.
I have ATI Radeon based laptop, default installation not properitary drivers (when I search for them I got message that it didn't found any). I read that my video card is supported by default drivers. lspci show: 01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS880M [Mobility Radeon HD 4225/4250] For me it look like corrupted video memory that show different data (saved when I watch youtube). Maybe it's drivers fault. I'm able to fix the issue for a while when I click show desktop icon. Don't know what's triggering this, sometime it look like everything is working fine. Before 14.04 I had 13.04 64bit version and everything was working fine, didn't have enough space to upgrade. But back then I had ATI catalysis drivers. ** Affects: xserver-xorg-driver-ati (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1333676 Title: Screen disappear and show chunks from memory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-driver-ati/+bug/1333676/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
