Re: [opensuse] Convincing 10.3/nVidia that my LCD can display 1024x768 - partially solved...
An earlier version I had used to run as a normal user. I once sent a query to nvidia and never got a reply. Have you tried running with the Toshiba as the only screen and also tried swapping one monitor with the other and reconfiguring to see what happens. Another trick to try is to rerun the driver pack with both screens connected.
This got me to go tinker a little... I swapped connections on the video card... and ran sax2 (just to see what it would do). This reset everything back to use the nv driver and a single desktop. Ok, then ran nvidia-xconfig... restarted X. Now I had the LCD displaying at 1680x1050. I didn't even know it could do that resolution. Teh TFT (which is supposed to run at 1680x1050) would only run at 1600x1200... and nvidia-settings wouldn't allow the correct resolution. After much tinkering and swapping cables back and forth I narrowed it down... it is ALL related to the HorizSync and VertRefresh values. If I set the values for the LCD to match those of my TFT, then I can set the LCD to display most resolutions from 320x200 all the way up to 1680x1050 (a few are out of range, but most display). I have set the LCD to 1024x768 (the documented top resolution for the LCD). and it is working at that resolution now... Of course the solution isn't 100% yet... but it's a start (and a painful path to get there). Next step... how do you find out what the correct frequency ranges are for a Toshiba 32WL56P LCD Television, and since it actually will display in 1680x1050, will it damage it to use that resolution (since the documentation with the TV states 1024x768)? One other minor issue... when I launch MythTV on that screen, it automatically switches back to 640x480 resolution... and I cannot find a way to stop it from doing that.

C. Hi Clayton, your manual should give you that info on refresh rates and you can try http://mythtv.org/ for that problem. Regards Dave P -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I sorted the MythTV problem.. was a well hidden setting I had changed a while back.... You would think that the TV manuals would have something somewhere about the refresh rates etc. for the LCD TV, but... nothing. I have put my own made up numbers into the xorg.conf (actually duplicated the TFT values) but I haven't stumbled on a combination that the nVidia driver will interpret as allowing 1680x1024.... but... as it is, it is working now in 1024x768 mode.... which is the documented max resolution. The only reason I would want to go higher... or keep poking away at this odd issue is that I have a related problem with MPlayer... if I start a video on the LCD, MPlayer plays the video as if it is on a 1680x1024 resolution monitor... strange.. more tinkering.. maybe I'll stumble on the "right" solution yet....

In the info I found with a bit of googling it was stated that the native resolution of the display is 1366 x 768 and anything larger is scaled down to that resolution. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Its unnecessarily hard to get sax to configure an nvidia card for two monitors or tv. If you've installed the nvidia driver you probably have an app from nvidia in "system -> More programs" called nvidia-settings. (/usr/bin/nvidia-settings). Once I got X to start I found that it was able to configure my displays so that they worked "on the fly". I've not been brave enough to save their cofnig to xorg.conf and restart x.... wcn Philipp Thomas wrote:

I use the nvidia-settings tool all the time. Never had any problems with it, including writing to the xorg.conf file. It's the easiest way to set things up. I traced the problem I was having... the nVidia tools were detecting the refrech freqs of the LCD TV incorrectly, and that was making it default to 640x480. I manually upped the values and restarted X... now no problem to drive the LCD at higher resolutions.
