Console corruption when quitting KDE

[Katch]

Driver works fine and performs well. Runs Guild Wars and Half-Life 2 under Cedega nicely.

Slackware x86 10.1 2.6.12 kernel - nV6880U Gainward GS - AMD64 Sandy 3700+

nVidia for Linux version - 1.0-8178

My problem is upon closing the KDE session and returning to the console I get a corrupted screen like so;



The console still responds and I can issue commands blind without problems.

I have narrowed the bug down to the nvidia driver as this bug doesn't happen if I use the nv or vesa driver in my xorg.conf.

any ideas?

If you're using a framebuffer, please disable it, and see if this problem reproduces.

Also, please generate and post an nvidia-bug-report.log.

Thanks,
Lonni

Perfect.

Disabling framebuffer by adding;

vga=normal

has cured this issue.

Is it possible to change the resollution of my console without re-enabling the framebuffer?

[Lethe]

Guys, I am on Slackware with FB on a GeForce4 MX440 SE and I found that adding the specific 'output' device and ignoring (unused) others fixed it:

# Nick 24/07/2004 - attempt to stop corruption exiting X
    Option         "ConnectedMonitor" "CRT-0"
    Option         "IgnoreDisplayDevices" "TV-0"

[Katch]

Thanks!

I now have my Frame Buffer running without causing any problems at all

Props to Nick, many thanks.

Hi,
because I have the same effect when changing to console I want to try your advices, but
@Katch - where have I to write vga=normal
@Lethe - where in xorg.conf should I insert your options
Thanks
Reinhard

[Lethe]

Reinhard,

You don't need the 'vga=normal' as that turns off the frame buffer - so leave that alone.

I also apologise - I missed out the section in xorg.conf where to place those lines - also you NEED to check Xorg.0.log to see what your CRT device is called... CRT-0 is normally OK on a single monitor, but check it out anyway.

OK:

    Option         "ConnectedMonitor" "CRT-0"
    Option         "IgnoreDisplayDevices" "TV-0"
