[Bug 31866] Re: Blue Vertical Lines in menus and other places in KDE/QT apps

[BigMess]

I had this problem too, and for me, lowering the color depth worked. It
seems like the video card is running out of memory, that's the cause of
the vertical lines.

Try this:

sudo nano /etc/X11/xorg.conf

Section "Screen"
...
(old value)        DefaultDepth  24
(new value)        DefaultDepth  16
...

And then, restart your X server [CTRL+ALT+BKSPACE]

I'm running Dapper, using a Dell Latitude CSx with a NeoMagic MagicMedia
256ZX video card.

BTW: Ubuntu with font anti-alias is *very* fast for a 500Mhz processor
and 2MB video.
