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 Ubuntu-X, 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)) 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/~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
