Whenever I choose to log out of KDE, rather than the screen shading, I get rather unpleasant looking lines on the screen. Attached is a screenshot.

When I had Redhat installed it had this problem to begin with, but fiddling with something caused it to behave itself. Now I'm running Slackware I've got the same problem and it's not going away this time.

My XF86Config file graphics device section is as recommended,

Section "Device"
Identifier "Intel i815e"
Driver "i810"
#VideoRam "4092"
# Insert Clocks lines here if appropriate
EndSection

I have tried uncommenting the VideoRam line but, no effect. Does anyone recognise the problem?

I've also heard that the i815e chipset can allocate system RAM for graphics memory above its 4MB dedicated memory. Is this so and can I put a higher value in the VideoRam field for better performance?

Regards

What resolution and color depth are you using?

You could try lowering one or the other and see if that helps.

Also try doubling the VideoRam "4092".

I was running 1024x768@24bit Depth. Reduced it to 16Bit and the problem was solved.

Strange that, I would have thought that you would have to increase the colour depth to get it to display correctly (I assumed it was because there wasn't enough colours to display the shading properly.)

Thanks for the help.

Glad to help.

Increasing the color depth would require MORE video memory.

Your video card just doesn't have enough memory for running at 1024x768 and 24bit.

You could either run at 800x600@24 or 1024x768@16.
