From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)
if SVGATextmode is invoked with or without a mode, running 'startx' later
on fails. On one system the KDE desktop gate painted properly but the
mouse leaves boxes behind and no clicks work, the display starts to flash
in large 1" suare boxes. On the other it never got past the grey-checked
pre-KDE screen. Had to hard reset.
rpm -q SVGATextMode : SVGATextMode-1.9-7
The system that goes crazy is using a Matrox Mystique 4Meg Frame Buffer
device, the other is using a ATI Pro Turbo 64 2Meg
This happens in 2.2.16-22, 2.2.18, 2.4.2 and 2.4.2-ac10-fixed
Commenting out the line I had in .bashrc fixed it on both systems.
Steps to Reproduce:
Actual Results: blinking blocks, or grey screen forever
Expected Results: KDE
SVGATextMode should never be used together with framebuffer-devices.
Since both of your cards are supported by framebuffer-drivers can't you use
fbset and setfont/consolechars instead ?
btw, SVGATextMode will no longer be part of the next RedHat Linux release (>7).
