Video artifacts on Gateway LT3103u netbook

I've switched to Archlinux from Ubuntu on my Gateway LT3103u netbook.  There is a strange issue where my video is distorted.  It is hard to describe in words, but it there are horizontal lines that are shifting and flickering.

This happens both at the command line and in an x session (Gnome).  Here is my lspci:

[colin@hectop ~]$ lspci
00:00.0 Host bridge: ATI Technologies Inc RS690 Host Bridge
00:01.0 PCI bridge: ATI Technologies Inc RS690 PCI to PCI Bridge (Internal gfx)

00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control
01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series]
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

I'm using the xf86-video-ati driver (although this same issue was occurring before I installed it).

Any help would be appreciated.

Re: Video artifacts on Gateway LT3103u netbook

I faced the same problem on my Acer Aspire 5920g (Mobility RadeonHD 3650). The only way to solve it I have found is to disable KMS (I created /etc/modeprobe.d/radeon.conf with the single line

options radeon modeset=0

and removed radeon hook from mkinitcpio.conf). But I had to disable compiz effects in KDE because it crashes otherwise (with KMS enabled everything was OK). So, still waiting for normal solution...

I have solved the problem with KMS. The parameter new_pll=0 should be past to the radeon kernel module. I added radeon.new_pll=0 to my kernel boot line in menu.lst and added

options radeon new_pll=0

in /etc/modprobe.d/radeon.conf. Now everything works fine with KMS enabled.

Just registered an account to say that this = WORKS AMAZING!

I had to boot as "nomodeset" just run anything other than 2d.

This has went into my file for my next install.

Thank you!~  1000x  Thank you!  Happy New Year.

Re: Video artifacts on Gateway LT3103u netbook

Welcome to the forums, JMBreitenbach, and thanks for the feedback. However, this is a rather old thread and time moves on fast, especially with a rolling release. Thus I will close this thread now (which means it will be kept read only).

Please have a look at our Forum Rules, especially at the Forum Etiquette.
