Hello everybody!
I just installed ubuntu-linux on an older notebook with a trident
cyberblade i7 onboard graphic card and I have several problems with
tridentfb from vanilla-linux-2.6.11
1. The kernel commandline seems to be ignored:
both
video=tridentfb:800x600,bpp=16
and
video=tridentfb,mode:800x600-16@60,fb
deserve 640x480-8
2. No matter what mode being selected the cursor is fixed to the last
line (after touching it the first time) and scrolling is only done in
this line (does not apply to ncurses apps which control the terminal).
3. clear doesn't clear the screen but puts the cursor to the first line.
(ncurses apps also seem to have this problem)
I took some screenshots:

As you can see, there is some strange noise at the bottom-right corner
in 800x600x16 mode (set via fbset).

What could I do about it?
