Some issues to resolve with XFree 4.0 yet

[Kevin Hendricks <khendricks@ivey.uwo.ca>]

Hi Kostas,

I have set up my XF86Config file to allow mode switching (with valid mode info)
by hitting the Cntl-Alt-KeyPad- and Cntl-Alt-KeyPad+ keys.  Unfortunately,
although the mode seems to switch the screen is very messed up.  Luckily, if I
keep hitting the key combo I get back to a good resolution.  I tracked this
back to fbdevxxxSwitchMode which uses a framebuffer ioctl (FBIOPUT_VSCREENINFO)
which in turn is handled in linux/drivers/video/fbmem.c and eventually calls
aty128fb.c set_var routine.

Something here is broken but I can't put my finger on what yet.  Does using the
key combo to switch modes on the fly under R128 work for you on your x86
machine?

Also, I tried to test this under the XFree86 running fbdev as its driver.  Each
time I tried this I ended up with a complete hard lockup (kernel went boom).  I
tried connecting from other machines on my home network but I got no response
at all.

This used to work fine under xf 3.9.17.   Have you tried this recently?

Thanks,

Kevin
