Thanks Adam. I checked with SAX2 and it shows the currently configured
graphic card correctly as an Intel i830. Meanwhile dmesg shows that my
laptop is using the vesa frame buffer driver. That makes me ask then,
what is the connection between the SAX configuration and what dmesg
shows?
***Hello again from Adam:
Putting on the Linux guru hat:
dmesg is showing you all the messages that Linux is booting up with. During the bootstrap, Linux uses information that is either setup by you thanks to Yast initial boot or factory boot (which will always use VESAFB) and whatever is on the LILO/GRUB commandline (go into yast, go to boot loader configuration, look at append commandline, see some software switches and you will see something=vesa and that will be the clue for using the VESA framebuffer driver).
Sax2,on the other hand, is the configuration utility for your X windowing system. You wont see jack of the final results until you reach runlevel 5 and go into X (the grey graphical screen with the x in the middle). You can also startx and play god there too.
Dmesg is for the text console and your hardware info for all runlevels; Sax2 is just for X.
My advice: adjust your window manger so you can run top or the process monitor and run some video. I use mplayer because it runs well and beats the crap out of the machine. Make sure to compile it for your laptop for best speed.
Try one video driver and then the other driver. Monitor the CPU utilization numbers. More CPU utilization on one is indicative of young, unoptimised video code.
