12.2 + 1920x1080 resolution
 
After 2 weeks of the nightmare that is KDE4 I've been driven back to S12.2 and the sanity of KDE3.5. However, I'm unable to get higher res than 1024x768. Monitor is a BenQ G222HDL and card is an ATI Radeon HD4760. Relevant section of my xorg.conf is:

HorizSync 31.5 - 50.0

# HorizSync 30-64 # multisync

As you can see I've mucked about a little bit with alternative drivers and resolutions and poked around via google without anything obvious popping up, but I suppose the driver is the issue. # randr only ever gives me 'can't open display'. I realize this is a new monitor on an older OS. Should I try the xf86 drivers from ATI, or will running xorgconfig do the trick with such a new card?
Thanx.

Just out of curiosity why did you go back to 12.2? 13.0 has official KDE 3.5.10 packages, there just a little harder to find.

I think it's because you have got HorizSync set far too low.

As an example at 1920x1080 @ 75Hz refresh you would need HorizSync to be at least 81kHz (1080x75) plus some more for flyback etc. Make sure your monitor can handle higher frequencies before you try though.

According to my googling, the BenQ G2222HDL wants:
Code:

HorizSync 24-83
VertRefresh 50-76

Thanks for the tips.
I *was* suspicious about the refresh rates, and as you can see I've opened them up a bit. However, the best res I can currently get is 1280x960. Here the relevant sections of my xorg.conf again:

It may be because you have the VertRefresh set to high. Try changing VertRefresh to:

VertRefresh 50-76, as allend suggested above.

I suspect that you are going to need another driver apart from the VESA driver. I have NO experience with ATI cards, but I believe that the ATI Catalyst 9.8 proprietary driver worked with Slack 12.2.

pargoo 09-03-2010 09:00 PM

I've got the rates on the recommended settings, and still stuck on 1280x960: H 30~63 kHz/V 50~76 Hz and no good. I have an ATI Radeon HD4670, so I'm guessing I need a new driver. Also using old version of Xorg - 1.4.2 on S12.2 I believe? - so will I need to upgrade to a more recent version?

pargoo 09-06-2010 02:24 AM

Try as I might I cannot find the Catalyst 9.8 drivers anywhere. ALL links either lead to dead sites or back in an endless circle to the ATI site and the latest - 10.8 - release. Anybody know if it's worth the effort to install this in 12.2, or if it works with that version of Slack? Of course, I'd need to upgrade to a much more recent version of Xorg, and I know nothing about doing that. Can I upgrade strait to the latest release of Xorg using slack packages or would I need to do it from source and would I need to recompile my kernel to do that?
As a PS: is installing KDE3 on 13.1 possible with the S13.0 packages available at ftp.osuosl.org?

pargoo 09-07-2010 11:30 PM

Okay, FINALLY found ver 9.8 on a not-very-obvious link at Xorg along with the howto(!) But I am totally confused about the numbering when it comes to x versions. When I'm told I need to upgrade to 6.8 they mean X11R6.8 - *nothing* to do with xorg-server, right??? The howto also tells me I need XFree86-libs, libstdc++, XFree86-Mesa-libGL and libgcc. Having gcc installed means I already have libcc, I believe. What about the others?
