Default Console corruption when quitting KDE

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.

Code:
# Dhax Moddified xorg.conf

Section "ServerLayout"

# The Identifier line must be present
# Each Screen line specifies a Screen section name, and optionally
# the relative position of other screens.  The four names after
# primary screen name are the screens to the top, bottom, left and right
# of the primary screen.  In this example, screen 2 is located to the
# right of screen 1.
# Each InputDevice line specifies an InputDevice section name and
# optionally some options to specify the way the device is to be
# used.  Those options include "CorePointer", "CoreKeyboard" and
# "SendCoreEvents".
   Identifier     "Simple Layout"
   Screen         "Screen 1" 0 0
   InputDevice    "Mouse1" "CorePointer"
   InputDevice    "Keyboard1" "CoreKeyboard"
EndSection

Section "Files"

# The location of the RGB database.  Note, this is the name of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (which are concatenated together),
# as well as specifying multiple comma-separated entries in one FontPath
# command (or a combination of both methods)
#
# If you don't have a floating point coprocessor and emacs, Mosaic or other
# programs take long to start up, try moving the Type1 and Speedo directory
# to the end of this list (or comment them out).
#
# ModulePath can be used to set a search path for the X server modules.
# The default path is shown here.

Default Re: Console corruption when quitting KDE

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;
Code:
vga=normal
has cured this issue.

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

Default Re: Console corruption when quitting KDE

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:

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

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

Default Re: Console corruption when quitting KDE

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:

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