What video driver should I use?

English Hardware
1

The computer I recently put together uses an ASUS M4785-M motherboard and has onboard an ATI Radeon HD4200 GPU.When I look in Yast Hardware, it calls it an RS780L [Radeon 3000]. I understand that the old fglrx driver won’t work on 42.2 or later. What proprietary display driver can I use, and where can I find it? Thanks, bob

There is none.
Not even fglrx (which doesn’t work on 42.2 any more) would support this card.

It’s only supported by the open source radeon driver that’s included in openSUSE and should be installed by default.

OK. The display IS working but only with VGA resolution and it makes some screens almost unreadable. How do I adjust the size of the display?

radeon should detect the size of the display automatically.

Please post your Xorg log, i.e. the file /var/log/Xorg.0.log, to see what’s wrong.

Maybe you added “nomodeset” to the boot options?
That would actually disable radeon, and use a generic driver.

5

No, I didn’t use nomodeset.

I’ve tried to post the log but the forum software says the log is too long and keeps kicking it out. Is there a particular section of the log I can copy and just send that?

Hi
Use SUSE Paste, set expiry to never though please… SUSE Paste

Copy/paste at https://paste.opensuse.org/ and post the link to it here.

OK. Here’s the link SUSE Paste

I only have time for a cursory glance, but it does seem that EDID is working and a bunch of display modes are detected/available, with the initial mode being set (1280x1024)…

If you check xrandr you should see other display modes available, and you should be able to set a preferred mode via your dekstop’s display utility on a permanent basis.

OK. HOW do I check xranddr?

And which display utility do you refer to?

11

Report with output from

xrandr

And which display utility do you refer to?

Which desktop environment are you using?

12

Fine. HOW do I do that? How do I “check xranddr” ? And what display utility do I use?

Thanks, Bob

Please look at man xrandr for details Note one d

xrandr can be used to adust display but first see what it says

14

Found the problem. When I used Settings, System Settings,Display Monitor, I found I could pull down the resolution settings, which then worked.

15

That is the display utility I was hinting at, but that’s why I requested the desktop environment you were using first :slight_smile:

The CLI utility can be used to provide the detected display modes as well.
