Configure 1600x800 screen resolution with radeon 5000 series (hd 5730)


Hello,

I know this is an issue that a few people have asked about, but spending the past few hours searching and messing around hasn't been productive.

I have a new system with an ati mobility radeon hd 5730 chip. As far as I know, there are new drivers in the works, but aside from some articles, I haven't found anything that specifically tells me how to get them installed/working (at least, so that it works for the 5000 series of radeon chips).

Has anyone had any luck with this yet? I'm just at the stage of installing, so I don't really care if it involves a different distro, etc. I've tried Ubuntu 9.10 and 10.04-alpha2, as well as Fedora 12 (from the live CD) and so far no luck.

At the moment, all I care about is getting the native 1600x800 working for my screen. I haven't a clue how do do that...it seems like I might be able to do this using xrandr, but I don't know how to create a mode properly.

Any suggestions would be greatly appreciated...

If you are using the vesa driver (as is likely the case) then xrandr will likely be limited to just vesa resolution.

When you tried Ubuntu 9.10, did you install the latest catalyst drivers from AMD?

Xrandr says:

Screen 0: minimum 800 x 600, current 1152 x 864, maximum 1152 x 864
default connected 1152x864+0+0 0mm x 0mm
1152x864 60.0*
1024x768 61.0
800x600 61.0

adamk75: Yes, I tried installing ati, radeon, radeonhd and fglrx drivers...fglrx explicitly said no no matching hardware was found when I ran aticonfig --initial. I don't know how to get the other drivers working though. I don't really know what to put in an xorg.conf file, but anything I've tried based on other references I've found online hasn't worked so far.

It is quite possible that catalyst 10.1 doesn't officially support the HD5730, unfortunately. Even if that's the case, it *might* still work. Have you tried creating a basic /etc/X11/xorg.conf file and forcing it to load the fglrx 10.1 driver?

Alternatively, you could grab the radeon driver from git (or cgit): git://anongit.freedesktop.org/xorg/driver/xf86-video-ati

And then build the newer version. That might require installing more parts of Xorg from git as well, though.

I did find that installing the fglrx modules worked...10.1 worked okay, and 10.2 worked...until I tried to login to KDE, at which point KDE hangs (but everything else seems to keep running).

This leaves me with the obnoxious 'ati unsupported hardware' watermark. Any ideas on how to remove that? I'd much prefer to go with the open source drivers...I suppose I'll give building it a try, though really don't know where to start.

At the moment, just so you know, the open source drivers do not even support 2D acceleration, just basic modesetting.

I was just about to suggest you ask on the phoronix forums for help getting fglrx working, but it looks like you already did :-)

A poster on the forums (Kano) has a script he includes in his own personal distribution that supposedly removed the watermark. You might want to check some of his posts to see if you can find any information about that.
