Desktop effects stopped working on Ubuntu 9.04
I have an Ubuntu 9.04 laptop with Intel 945 graphics adapter. Desktop effects worked until this morning when I connected it to an external monitor. After disconnecting the external monitor and restarting the laptop, desktop effects stopped working. Does someone have an idea how to reenable them? -- Ori Idan ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

what happens if you run ' compiz --replace ' from the terminal? 2009/10/13 Ori Idan o...@helicontech.co.il: I have an Ubuntu 9.04 laptop with Intel 945 graphics adapter.

After disconnecting the external monitor and restarting the laptop, desktop effects stopped working. Does someone have an idea how to reenable them? It's a known bug in the Intel driver: You placed the external screen to the left/right of the laptop screen, causing the effective screen width to be one that the Intel Driver does not support 3D acceleration for, thereby causing compiz to turn off effects. If effects won't turn on, check /etc/X11.conf under section Screen subsection Display to see it doesn't still list a too-wide screen (your laptop is probably 1024 or 1280 pixels wide). When this happened to me, I deleted the Display altogether and let Ubuntu re-figure it out itself, but a sudo dpkg-reconfigure xserver-xorg might be helpful. And from now on, when you connect an external monitor, just be sure to place the screen above/below the laptop screen rather than to the left/right of it. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Thank you very much.

That only works if you have a relatively new graphics card and a relatively new LCD monitor. Or if you want the default settings for various options. If you want to change the defaults, or you have a CRT (especially and old one) you need a conf file. A really bad combination is a relatively modern display card such as an NVIDIA or ATI with 128m of RAM or more and and an old CRT. I don't know if it is an UBUNTU thing or the real default, but control- alt-plus and control-alt-minus (switch resolution) and control-alt- backspace (kill X) are disabled. So you can't keep switching until you get one that works and then set it permanently, or keep killing X until you get a text screen.
