I've tried to reproduce this, and failed. Please give me a copy of your xorg.conf file. What I did was install debxo 0.4 gnome.img, then investigate /etc/X11, only to find that xorg.conf is no longer there in that version. So I don't know how you have one, and I don't know what you have in it. I tried placing just the Option line you specified in an empty xorg.conf, but X would not start, complaining of syntax error in the file. Then I copied an xorg.conf from rsync://updates.laptop.org/build-ubuntu, and looked through it. Then I installed the Debian x11-apps package, and did some performance timings, using "time x11perf -time 1 -repeat 1 -all", with different configurations, to try to reproduce your observation; 1. debxo 0.4 standard gnome configuration, without xorg.conf file, the test took 29m 43s, 2. debxo 0.4 standard gnome configuration, with xorg.conf file as is from build-ubuntu, the test took 29m 45s, 3. debxo 0.4 standard gnome configuration, with the above xorg.conf file, with your Option line added to the Driver section, the test took 29m 47s. > Why is limiting the video ram to half the size make it faster?
