[Bug 260436] Re: Unable to force screen resolution with vtswitch/splitter
Glad I could help 3vil. It's a shame that there's no mechanism for ordinary people to achieve the same thing, for whom manually editing xorg.conf is a step too far. After all it only takes three gui fields and a go button! All the other tools are already in place - gtf, gnome resolution config, etc. I often wish I had the means to author this kind of software myself but I think it's a bit beyond me. -- Unable to force screen resolution with vtswitch/splitter https://bugs.launchpad.net/bugs/260436 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 260436] Re: Unable to force screen resolution with vtswitch/splitter
@Cefn: Thank you very much for posting the gtf command and xorg changes! I ran into this issue today while attaching a machine to a KVM and could not get it to work until I saw your workaround. It's pretty frustrating when the GUI gives you no options other than 320x240 and 640x480 because DPMS doesn't work through the KVM. -- Unable to force screen resolution with vtswitch/splitter https://bugs.launchpad.net/bugs/260436 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Could you reopen this bug. I can reproduce it and still have a KVM which prevents the autodetection capability from working.

[Bug 260436] Re: Unable to force screen resolution with vtswitch/splitter
I'm referring to your request a few hours ago... can you force the resolution using the xrandr command line tool? Yes you can force it using xrandr, assuming that you have edited xorg.conf properly. I've carried out these steps and proven that you can force the correct resolution regardless of auto-detection, through a KVM which suppresses the ordinary auto-detection signals. My suggestion is to permit users to manually specify modes in the graphical tool, and have the gnome screen resolution tool make the required changes to xorg.conf just as it does today with virtual resolution. It's to add this feature to the ubuntu environment that the original request was about - not having to manually edit xorg.conf. It's for this reason I'd like to keep the bug open and provide any maintainer with more information about the request. -- Unable to force screen resolution with vtswitch/splitter https://bugs.launchpad.net/bugs/260436 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 260436] Re: Unable to force screen resolution with vtswitch/splitter
The graphical tools DO list the same options as the xrandr command. That means that if the autodetection has failed to identify a valid mode by autodetection, you are screwed unless you like to edit xorg.conf. Then these options show up in xrandr and in the graphical tool. To fix the problem I had to manually generate a line using gtf thus... c...@cefn-linux-dell:~$ gtf 1440 900 60 # 1440x900 @ 60.00 Hz (GTF) hsync: 55.92 kHz; pclk: 106.47 MHz Modeline 1440x900_60.00 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync Then weigh in and edit my xorg.conf, based on the output identifiers reported by xrandr. The xorg.conf for my specific monitor follows, but it took me the best part of half a day to work out enough about this problem to solve it. My mother wouldn't stand a chance, even if she could tell perfectly well what the values of horizontal pixels, vertical pixels and refresh rate actually were, since it involves manually editing config files in mysterious and ill-documented ways! Since the bug/feature request is about the need to avoid manually editing config files, and I'm providing information about it, I don't know why you keep re-closing it? You only gave me an hour to get back to you this time before re- reporting the bug/feature request as closed. Maybe I don't understand the status reporting properly, or the nature of the bug and where it currently is in the system, so forgive me if I'm confusing matters somehow and let me know how to file this request properly. Anyway here's the example xorg.conf which could be generated by the graphical tool from those three parameters to help my mum out. Grandr already does the Virtual resolution bit automatically just the same way. What I'm suggesting is adding three fields to the gui tool (in my case 1440,900,60) and an invocation of gtf, followed by an automatic edit of xorg.conf and a message to re-log-in, just as it does with the Virtual resolution line.

[Bug 260436] Re: Unable to force screen resolution with vtswitch/splitter
if the xrandr command line doesn't list those modes too the issue is rather an xorg one, the xrand interface should list some choices which make sense in such cases, that's not specific to the GNOME GUI ** Changed in: xorg-server (Ubuntu) Sourcepackagename: gnome-control-center = xorg-server Status: Invalid = New -- Unable to force screen resolution with vtswitch/splitter https://bugs.launchpad.net/bugs/260436 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

As you say, with a splitter and multiple monitors attached, this is beyond X's autodetection capabilities. It sounds like your request is to have a functionality in the GUI tool for manually specifying settings in this case, so I'm reassigning to the GUI tool. ** Changed in: gnome-control-center (Ubuntu) Sourcepackagename: xorg = gnome-control-center -- Unable to force screen resolution with vtswitch/splitter https://bugs.launchpad.net/bugs/260436 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
