14.04 on 201305-13641, AMD hybrid graphic system. 00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8610G] [1002:990f] 01:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M] [1002:6660] This issue might not relvant to Intel driver, since this system still affected and it does not have an Intel graphic chipset.
This issue: CANNOT be fixed by using the v3.15-rc3-utopic mainline kernel CAN be fixed by using the latest xf86-video-ati (ddx) from git (following this guide http://www.x.org/wiki/radeonBuildHowTo/ ) For the last step to get xf86-video-ati (ddx) work, I need to create the xorg.conf file in /etc/X11/ (there is no such file when this happens) After reboot, the display is back to normal, so I didn't go on with the following packages in that guide.
