Question Weird screen in high resolution (1600x1200)

Hi,

I get a strange image when i'm using a high resolution (tested with 1600x1200) with nVIDIA official driver. Each line on the screen seems to be shifted on the left; it makes me think about hsync/vsync issue. I believe the ModeLines are good, because it's working perfectly with the free driver (bundled with XFree86).

Another weird thing, in this section :

Code:
  Subsection "Display"
    Depth       24
    Modes       "1280x1024" "1024x768" "1600x1200"
    ViewPort    0 0
  EndSubsection
In this case, XFree starts in 1280x1024, but the problem is still there, because 1600x1200 is on the same line.

I don't see any errors in the XFree logs. Drivers 1.0-4363 and 1.0-4496 behave the same. I tried the "IgnoreEDID" option, which doesn't help. I also tried with twm instead of WindowMaker.

Note: The nVIDIA logo at XFree startup is ok.

Config:
  • Linux 2.4.22 (preempt+lowlat)
  • Glibc 2.2.5
  • XFree86 4.3.0
  • Drivers 1.0-4496
  • Geforce 3 Ti 500 64 Mo

I'm running out of idea... Does anybody have one ? Thanks in advance

Hey

Try to use the program (gtf.c) on this site to generate modelines for you:

http://gtf.sourceforge.net/

I Hope it helps.

PS: If you want X to start in 1600x1200 you should change the resolution order:

Modes "1600x1200" "1280x1024" "1024x768"

Hello,

Thanks for you answer, Dulley.

I made the modelines with the gtf program, bundled with XFree, and the modelines work perfectly with the nv driver.

The resolution are also sorted from the biggest to the smallest. I just wanted to say that when i put 1600x1200 at the end, XFree starts in 1280x1024 (normal), but the problem still occurs.

That's why i think it's not a problem of frequency or modeline, but something with memory maybe.

Default I had this exact problem

I am running an LFS system and had this problem with my version of XFree86. After trying everything that I could think of, I installed RedHat 9 on a different partition and tried it out. It worked perfectly. So, I concluded that there was a problem with my X installation. I removed xfree86 and installed the binaries that are available from xfree86.org:

ftp://ftp.xfree86.org/pub/XFree86/4.3.0/binaries

You may want to try backing up your current X installation and installing those binaries and see if that does the trick - it worked for me.

Default Also...

It may be a good idea to see if there are updated X packages for whatever distribution your using. I'd check into that before installing the X binaries.

I'm running LFS too (3.3). You may be right, my XFree is borked... I'll try binaries tonight.

Thanks !

Default LFS

I'll bet that's it then. I tried applying several patches from RedHat 9's XFree source rpm, but couldn't get it to work that way either. The binaries were the only thing I could make work, so... I don't know what it is about LFS that causes the issue.

It's working ! Thanks a lot for your sugestion

I decided to try to recompile XFree (while still following instructions on BLFS CVS). The first time, i specified some optimisation flags (DefaultGcc2i386Opt) in host.def (like the first time i compiled it). As expected it didn't worked. So i did it again without the flags (#define DefaultGcc2i386Opt commented out), and it worked !

I also commented #define XF86CardDrivers, i didn't knew if the nvidia driver was relying on something in this list.

I attached my host.def

Thanks again for your help
