I had the same problem on my Asus EEETop 1602. It looks like I could solve the problem by disabling the framebuffercompression in xorg.conf - maybe you give it a try: I quote from jk from a similar bug report discussion (#305227):
"Adding "Framebuffercompression false" like below did the trick. Section "Device" Identifier "Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller" Driver "intel" BusID "PCI:0:2:0" Option "FramebufferCompression" "false" EndSection " dirk -- [i945GM] screen goes black about once per day after upgrading to latest intel drivers https://bugs.launchpad.net/bugs/384730 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
