[Bug 959343] Re: Incorrect screen resolution
This version is no more supported and is not a 'security' problem; so does not expect a backport ** Changed in: gnome-control-center (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/959343 Title: Incorrect screen resolution To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/959343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 959343] Re: Incorrect screen resolution
The bug is still present in 12.04. The workaround of disabling GPU scaling through the nvidia-settings utility still works. But that still leaves the login screen with an incorrect resolution. Additionally guest sessions will always start with an incorrect setting, so after starting a guest session you have to start the nvidia settings utility, then disable GPU scaling, then manually set the correct resolution. That makes the workaround way too cumbersome to be acceptable, especially for the guest account which is expected to be used by less experienced users. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/959343 Title: Incorrect screen resolution To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/959343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 959343] Re: Incorrect screen resolution
I tested the 1024x768 resolution with all the possible refresh rates that gnome-display-properties permits for this resolution. It makes no difference which of the refresh rates from 52 to 56 Hz I choose, the output always ends up being 1280x800 at 59Hz. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/959343 Title: Incorrect screen resolution To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/959343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 959343] Re: Incorrect screen resolution
I finally found a way to get the correct screen resolution on the output. In the nvidia-settings utility there is a section called DFP-0 where there is a Flat Panel Scaling box. In that box I disabled Force Full GPU Scaling The Flat Panel Information claims the native resolution of my projector is 1280x800 (which is incorrect). So something autodetects the resolution as 1280x800 and set the GPU to do the scaling such that the projector doesn't have to do it. This should help narrow down the location of the bug. But disabling Force Full GPU Scaling is a suitable workaround. Now I just need to figure out how to make the change permanent. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/959343 Title: Incorrect screen resolution To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/959343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
