[Bug 404426] New: Xorg does not use the resolution set by sax2 for second display
https://bugzilla.novell.com/show_bug.cgi?id=404426 Summary: Xorg does not use the resolution set by sax2 for second display Product: openSUSE 11.0 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org AssignedTo: sndirsch@novell.com ReportedBy: sven.burmeister@gmx.net QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- I have an ATI x1700 in my notebook with a 1440x900 display and a second display attached to it, which can display 1280x1024 pixels (LG Flatron L1919s). I am not able to set-up the second monitor in a way that it displays 1280x1024, it always uses 1024x768. Idealy the notebook display should be disabled and only the second display working while attached. What I have done is: enabled "Dual head" in sax and set the second display to LCD 1280x1024 60 Hz as well as the resolution it should use to 1280x1024. I tried Clone mode as well as Xinerama and even tried to use the ati binary driver (repo-version as well as the latest from their website). I have also tried to set the notebook's display to just 1280x800, in case the issue is caused by the first display using a wider resolution than the second display is able to display. I'll attach the Xorg log and xorg.conf. If you need any other variation of those files, please let me know. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Sven: one thing, could you set Virtual to 1280x1024 in your xorg.conf display subsection of the screen section?
This shouldn't matter, if the panel is active at Xserver startup time. Then automatically a virtual 1440x1440 fb would have been allocated. As the configuration looks to me, it seems you have configured your panel to be 1280x1024, and the external output to 1280x800. I don't think this is exactly what you wanted to do :-) Bear with us, dual-head config in sax2 isn't exactly trivial - in some cases the "secondary" head can even be the PANEL, so you have to try out both variants. Using 1280x800 looks wrong anyhow, though. You should better try to configure a single 1440x900 display, and use either krandrtray or (better in this case) gnome-display-properties to switch the output and resolution on-the-fly.

The problem is that this is not my notebook and we managed to get it working with xrandr after we tried all kinds of combinations and resolutions. Since it works now and proper resolution is pretty important for ffeling comfortable when working with opensuse, I hesitated to change anything.
Does it work directly after X startup? In that case, the xorg.conf is perfectly fine and contains everything needed.
I am not familiar with xrandr, we just looked on the internet for the commands to use and tried it. So if you could tell me which files except the xorg.conf I have to save in order to be able to restore the current state after trying out a different resolution, I will provide the data.
xrandr doesn't have persistence, everything is restored to the config in xorg.conf on Xserver restart. And no, there is no way to save/restore a state you created with xrandr calls.
If sax2 is not the best option to configure dual-head, would it not make sense to tell the user so, or at least give a hint within sax2 that if things do not work out, he should try krandrtry or gnome's equivalent?
For persistence, it still is the best option. The desktops are slowly getting to a state where they will offer a better solution. AFAIK both the newest krandrtray and gnome-display-properties have persistence. It looks to me like we could close this bug, do you agree? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I fully agree.

Yes, this looks like a misconfiguration.

Yes, I think this was mixed up with 1280x1024.
You should better try to configure a single 1440x900 display, and use either krandrtray or (better in this case) gnome-display-properties to switch the output and resolution on-the-fly.
Right, here you're on the safe side. Closing as fixed. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
