Bug#605318: radeon: horizontal interference lines on screen

My workaround is to configure the display settings so the desktop is upside down, at which point I get a prompt asking if I want to keep or restore the new settings. While that prompt is up, the display still has the lines on it, but as soon as I hit ESC to revert the upside down change, everything goes normal and stays that way until the next cold boot (very rarely do the lines come back after putting the laptop to sleep, and if it happens I can just flip the display upside-down and back to fix it). --MattOn Mon, Sep 12, 2011 at 3:48 AM, Jonathan Nieder jrnie...@gmail.com wrote: found 605318 linux-2.6/2.6.32-35 quit Hi, Matt Pandina wrote: I too was experiencing horizontal lines (so bad that I could barely see the screen!)

Let's track them separately: Mike's effect will continue to be tracked at #605318, while Matt's is #641633. OK - made a video with xvidcap and uploaded it to youtube but it does not show any interference. Don't know if that itself is diagnostic.

Bug#605318: radeon: horizontal interference lines on screen
Hi Jonathon, glad you are onto this. The problem is much less on mine as each flash is only about 1-2 cms long and I guess 1px wide, and they only occur on certain parts of the screen on solid dark colours and appear to be completely random. They vary in colour. They show up on the grey background of gwenview well, and on Chromiums top window frame, which I have dark blue, and that gets blue flashes. Strange, but I dont see any interference on my desktop background, which has a large area of solid black. This is on a testbed install of Crunchbang Statler, which is pretty much pure Squeeze, for checking out stock kernels and open source drivers and have been trying to get a video screenshot to send to you but I can't get vnc2swf to work, as it bombs out with an error. If I can get some video of it, I will send it so you can see exactly what it looks like. firmware-linux-nonfree is installed. I have not tried sid kernels, but I also have a testbed install of Mint LMDE (based on Testing), and the problem seems to be fixed in that with the current kernel and radeon driver, though suspend does not work properly if I remember correctly. I have everything working perfectly on my Squeeze production install with this workaround, which is to use: Kernel-2.6.34-2.dmz.3-liquorix-amd64 x86_64 + Catalyst version 10.12. Graphics info : Card ATI Mobility Radeon HD 3400 Series X.Org 1.7.7 Res: 1600x900@60.2hz GLX Renderer ATI Mobility Radeon HD 3400 Series GLX Version 3.3.10317 Compatibility Profile Context This is the first combination of driver and kernel I found that works properly on this machine in Squeeze, including working resume from suspend to ram, so I am sticking to it on my production install. I removed the stock debian kernel so I don't get updates to it any more when I upgrade. I can do a new testbed install of straight Debian Squeeze and give feedback from that if it will help.

Bug#570517: No resume after suspend to ram
Installed latest kernel and suspend/resume works now. The wifi fails to reconnect after resuming though. This is with the radeon driver. Unfortunately, I am getting interference with radeon, though it is not as bad as it was, and only seems to occur on solid dark grey bits of the screen, like the kde4 desktop folder widget and the blank spaces either side of the image in gwenview. FGLRX 10-11 works well but has suspend/resume issues. This problem seems to vary depending on desktop environment. The above applies to kde. Running lxde, suspend/resume works but leaves me with a dim screen which I can't yet find a way to get back to full brightness. Wifi is working after resume though.. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
