I am having the same issue. My graphic card is RS690M [Radeon Xpress 1200/1250/1270]
The workaruond for me waas to add "nomodeset" in the GRUB_CMDLINE_LINUX_DEFAULT option of the /etc/defaut/grub file. Like this : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" Then launch update-grub and reboot This makes the flickering go away but it disable the ability to change the screen resolution -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1326048 Title: Xubuntu 14.04 screen flickers (VGA: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)) Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: Hi all, after a fresh install of Xubuntu 14.04 LTS the screen flickers continuously. The VGA is :: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) The problem didn't take place on earlier versions of Xubuntu (or at least it wasn't as visible since I didn't notice it) Now it is very disturbing and tiring for the eye. It is much more visible with brighter screen and seems more visible immediately after log in, but it might be because after a while the eye gets used to it. It might be worth noting that I do not have any option to change the refresh rate from 59.1Hz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1326048/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
