Virtual screen with Intel GMA3100 ?

alexander neundorf's picture

Last week I upgraded my development machine, from a AMD Athlon XP 2000+ to an Intel based one, featuring GMA3100-based onboard graphics.
Everything's working smoothly that far, I have only one issue: "Virtual" keyword in the "Screen" section seems to be ignored.
This was working since my very first Linux installation in 1996, so I'm really used to having a big virtual screen.
This is on Slackware 12.1, using xf86-video-intel 2.2.1.
Any ideas ?

Removing features...

It seems I found it:
http://lists.freedesktop.org/archives/xorg/2007-September/028145.html

So this functionality was removed Sad

Now I "just" need a way to get it back. Build current xorg from sources ?

Try this hack ?

Kind-of working again

So, I tried the hack, the patched hack, and the hacked hack.
Works Smiling
You can get it here:

So, get the sources, modify them so they match your actual resolution instead of 800x480, decrease the timeout from 0.1s to 0.01s (feels much smoother), and voila !

$ xrandr -fb 1400x1150
$ i810_pan &

And I have an working virtual screen again ! Smiling

Only issue so far: neither kicker nor kwin detect the new virtual size, so kicker is a bit short and kwin only considers the original screen size for automatic window placement and snapping.
