| |
I want to report a bad interactivity which happened in my desktop running the latest kernel (2.6.25-rc3-00081-g7704a8b).
I tried to play 'flightgear' and the desktop became _very_ slow while flightgear was "loading scenery objects" (a task which never finished and I could not play it).
The desktop is a P4 @ 3.0 GHz, 512MB, with the nv graphics driver.
I ran 'fgfs' firstly as a regular user (mafra) and tried to execute Ingo's cfs-debug script as root in a terminal (mrxvt) which had 3 open tabs. It took minutes to switch tabs and run cfs-debug-info.sh, which completed its job only after I managed to kill flightgear (after more than a couple minutes). The result is here:

[ I want to emphasize that I started the script while the system was slow, waited a few minutes, killed flightgear, and then the script finished its job. ]
As I have the group scheduler enabled, I tried to run flightgear as root to see what happens. I could not even start to run the debug script, because each letter I typed took many seconds to appear.
The mouse pointer however was responsive, but Window Maker wasn't. I tried to switch desktops, and after a few minutes the pressing of "Alt+5" took effect and the desktop 5 appeared ok in the screen.
Then I tried to go back to desktop 1 with "Alt+1" and after exactly 12 minutes I gave up and hit "Ctrl-Alt-Backspace". After 5 or 10 seconds X was killed and everything was normal again (no need to reboot).
Is this experience normal? I know that trying to play a game without 3D is a crazy thing, but it didn't feel _fair_ to wait minutes to see the result of a key press.
