** Summary changed: - External monitor loss - intel 945 + External screen blanks black/gray/white unless Framebuffer Compression is turned off
** Description changed: Binary package hint: xserver-xorg-video-intel I use my laptop (1st gen Macbbok) with external monitor. The display is a HP w2207h, and the resolution is 1680x1050. I can change the resolution without problem. Then the monitor is slip away few hours later. I try restart the X server, but on the monitor I doesn't see anything. So I get a black display on HP's screen, and on the Macbook's monitor I see the GDM. I can't find anything in the logs, everything looks good. cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=8.04 DISTRIB_CODENAME=hardy DISTRIB_DESCRIPTION="Ubuntu hardy (development branch)" % dpkg -l xserver-xorg-video-intel | cat Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-f/Unpacked/Failed-cfg/Half-inst/t-aWait/T-pend |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==========================================-==============================-================================================= ii xserver-xorg-video-intel 2:2.2.0.90-2ubuntu2 X.Org X server -- Intel i8xx, i9xx display driver + + [Workaround] + Edit your xorg.conf to include the following Option in the Device Section of “Configured Video Device”: + + Section "Device" + Identifier "Configured Video Device" + Option “FramebufferCompression” “off” + EndSection -- External screen blanks black/gray/white unless Framebuffer Compression is turned off https://bugs.launchpad.net/bugs/193419 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
