Intel i950 external monitor + compiz window size problem

[Todd Morgan]

Binary package hint: compiz

I have a Toshiba M105-S3041 with an Intel i950 video card (max screen res. 1280x800). In addition I have a 22" Acer monitor (max res 1680x1050). I just installed Ubuntu 7.10 last night and I have the following problem when "Desktop Effects" are enabled.

I use my external monitor exclusively and have the BIOS set to go straight to the external monitor upon bootup. When booting up my external monitor shows my desktop perfectly at 1680x1050. When I open a window (any program) it automatically opens in the upper left corner. When I maximize the screen it only maximizes to the equivalent of a 1280x800 window in the upper left corner. If I drag the window to the center of the screen and hit maximize it then fills up the entire 1680x1050 screen however when you click anywhere on the window it resizes BACK to the 1280x800 resolution in the upper left corner. I've installed the compiz-settings-manager and tried disabling everything and none of the changes had an effect. The only solution I have is to disable desktop effects entirely.

When I was running Ubuntu Feisty and installed compiz-fusion it worked beautifully. I tried using the xorg.conf file that I saved from my Feisty installation, but that did NOT fix the problem with my 7.10 installation

I have posted this bug to the Ubuntu Forum and at least a few other folks with the same setup (ie laptop with an intel video card and using an external monitor with a higher resolution) have experienced this same problem.

I can confirm this on a Dell D820 with a 1280x800 internal screen resolution and an external monitor with the resolution at 1280x1024. Disabling desktop effects fixes the problem.

Same problem, with this hardware: Dell latitude D820 / Intel graphics (1680x1040 internal lcd), monitor viewsonic 1440x900.

Maximization attempts when using the external monitor actually do 1024x768 which is very annoying.

Using 7.10 final.
