[SOLVED] LCD shows vertical lines

[Verlager]

I am using VL-SOHO 5.8 on a EliteGroup (ECS) 761GX-M754 motherboard with a Sempron 3000mHz CPU. The Viewsonic LCD V720 works fine in Windows, but not in any Linux I have tried. I get vertical lines spaced about 1" apart. What can I do? Here is my ddcprobe and xorg.conf:

Does the problem persist if you use the VESA driver?

Does the problem persist if you use the VESA driver?

I am using the on-board video VGA port, but if this isn't fixed today, I will order a $50 nVidia PCI Express video card from TigerDirect.

How do I try the VESA driver? Won't that be old tech and cruddy?

[lagagnon]

I agree with saulgoode - the "sis" driver can be a bit clumsy. Edit your /etc/X11/xorg.conf file as root in a terminal and change the line: Driver "sis" to Driver "vesa" and see if that helps.

[rbistolfi]

I have the same chipset and I can confirm the vesa driver works better then the sis driver.

[Verlager]

Solved! Works all right, but google earth can't find a driver and movies look like crap. I have ordered a $50 video card which will solve much, I believe.

[rbistolfi]

Yes, Google earth needs 3d accel, I think, and yes, my movies looks not so good here too. But is my card, I have seen good quality with vesa in other cards.
