Old toshiba laptop: switching video modes is SLOW
 
Hello,

I'm using a toshiba "satellite 2410" laptop, 2GHz cpu with a geforce4 420 "go" integrated on board. Using the drivers suggested by nvidia.com for this card (NVIDIA-Linux-x86-96.43.13-pkg1.run) switching between resolutions in X, or from a textmode console back to X takes several seconds for each change. Switching from an X session to a text console however is immediate.

This is kind of annoying especially when i'm trying to cycle through the available screen modes. It also causes X to take much longer to start (i don't know what xinit, startx, or the nvidia drivers are doing) This problem doesn't happen with the vesa or fb drivers, switching between modes/resolutions is fast and immediate using these. I don't see anything suspicious in my /var/log/X*.log files using the nvidia drivers.

Is there a xorg.conf option or something that i should use to skip some unnecessary checks or whatever?

Thanks,

- delt.

As long as it's below say 5 seconds, it's probably normal.

Why do you need to switch to textmode that often anyway?

Takes about 6 or 7 seconds just to change resolution.

I often switch between different X sessions, and sometimes between graphic modes on the same session. Weird thing is, even if two X servers are running at 1024x768 (this laptop screen's normal mode) switching between them takes the aforementioned 6-7 seconds delay to switch to the other server, + a few extra seconds for screen re-initialize or whatever.
