Description John T. Shaw 2004-03-09 14:59:55 UTC
My system locks up when I switch to a virtual terminal from XServer.

I envoke XServer with:
xinit -- Xvesa :0 -screen 1280x1024x32 -3button -mouse /dev/psaux,5 -dpi 96
-shadow -nolisten tcp

my .xinitrc:
/opt/fdo/bin/xcompmgr & startkde

I am used jhbuild to build the server from CVS yesterday, version reported is
11.0, vendor release is 6,600.  I can't find a build number anywhere.

I should probably mention I use the Vesa frame buffer in linux as well and I am
running the 2.6.3 kernel.
Comment 1 John T. Shaw 2004-03-10 06:50:43 UTC
The lockup was casued by the -shadow option, I am not using it anymore and it
works fine.
Comment 2 Stéphane Loeuillet 2004-07-26 06:58:50 UTC
so, you use both VESA for the console and X ?

it looks like a bad idea to have both using the same 'driver'
each one could have a different 'internal state' for the same piece of hardware
so, messing the two together could bring you big trouble (like garbled screen at

i don't know what part of video memory this option tries to copy to main RAM
(what shadowing means to me).

closing it as 'not a bug' as it is more likely a 'miss-configuration' (using 
vesa on both sides looks bad IMHO)

if someone disagree, fell free to reopen
