You have been subscribed to a public bug: Trying to achieve: Get a more stable graphics environment up and running
Steps to take: basic ubtuntu 14.04 install. Boot up and run for a few minutes and then ... What happens: After running for a few minutes the graphics gets flacky. What should happen: Graphics should not get flaky. I have just installed ubuntu 14.04 on my new thinkpad t450s. Everything basically works, but something is very flaky about my keyboard or display or both. After running for awhile some apps (E.g., thunderbird and sometimes emacs for example) will display garbage. If I refresh by moving the screen around or changing buffers/tabs/etc. they can often recover. I see that there is an [Intel(R) Graphics Installer for Linux* 1.0.7](https://01.org/linuxgraphics/downloads/2014/intelr-graphics- installer-linux-1.0.7). I am leery about just loading this and running it. Any suggestions about how I should proceed? $ sudo lshw -c video *-display description: VGA compatible controller product: Broadwell-U Integrated Graphics vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:63 memory:e0000000-e0ffffff memory:d0000000-dfffffff ioport:3000(size=64) $ modinfo i915 | head filename: /lib/modules/3.16.0-31-generic/kernel/drivers/gpu/drm/i915/i915.ko license: GPL and additional rights description: Intel Graphics author: Tungsten Graphics, Inc. srcversion: 9929027A8A6F05972AD6986 alias: pci:v00008086d000022B3sv*sd*bc03sc*i* alias: pci:v00008086d000022B2sv*sd*bc03sc*i* alias: pci:v00008086d000022B1sv*sd*bc03sc*i* alias: pci:v00008086d000022B0sv*sd*bc03sc*i* alias: pci:v00008086d0000162Dsv*sd*bc03sc*i* $ uname -a Linux mypad 3.16.0-31-generic #43~14.04.1-Ubuntu SMP Tue Mar 10 20:13:38 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux ** Affects: linux Importance: Undecided Status: New ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: Confirmed -- Graphics unstable on Ubuntu 14.04 and 14.10 using Intel HD Graphics 5500 https://bugs.launchpad.net/bugs/1432194 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
