Xrandr 1.2 S-video output to TV is trapezoidal using ATI Radeon 9250 PCI
Greetings Everyone,
I have been searching for an answer to my problem for about a week using Google. I have not found any threads on any forums that resolve this problem. I am currently running Slackware 12.1 on Linux kernel 2.6.27.5. I believe that the resolution I am outputting to S-video is the culprit. When I try to add a resolution to S-video output I get this error: Code:
xrandr --addmode S-video 640x480 Code:
lspci -v Code:
xrandr --newmode "640x480_60.00" 23.86 640 656 720 800 480 481 484 497 -HSync +Vsync |
Xrandr 1.2 S-video output to TV is trapezoidal using ATI Radeon 9250 PCI
So I've been trying to resolve this problem with fglrx instead of the drivers that come with Linux kernel 2.6.27.5, but I can't seem to get it to install properly. Are the proprietary drivers better than the kernel drivers? I was also talking with a friend and he told me I should post my xorg.conf and Xorg.log here in case there is some information in them that could help. As both of those are quite long, what parts are important for diagnosing this problem? When looking for the proprietary drivers, I found out that ATI has discontinued the Radeon 9250 video card. Could they have not included support for this card in the latest Catalyst update? I am a total loss. If I come across any solutions I will be sure to include a link in my next post.

I'm new to dealing with video card config with xrandr as well. I do however have the same card as you and have been able to get my S-video output working well under ubuntu 8.10.
I got a similar error to yours when trying to add resolutions until I used 800x600. I'm not sure that these lines are all necessary, but here is what worked for me: force video mode: $ xrandr --addmode S-video 800x600 I then made the display active using the following lines: $ xrandr --output S-video --set load_detection 1 $ xrandr --auto For what it's worth, I couldn't get things to display properly with the fglrx driver. xrandr version: 1.2 kernel: 2.6.27-9 Hope this helps! |
Xrandr 1.2 S-video output to TV is trapezoidal using ATI Radeon 9250 PCI
I can get an S-video output resolution of 800x600. I don't think I was too clear in my initial posts though. When I use the default S-video output, I get a picture that is slightly more narrow at the top than at the bottom. I have tried it on two televisions, and both get the same results. The picture is fine, it's just not square is all. I have been searching for a couple of months and I have yet to come across a solution for this problem. I also use your method when I am not cloning my desktop. I do this set of commands to get a picture just for my television using xrandr:
Code:
xrandr --output S-video --set load_detection 1 |
