As I have been using the same setup for several years I'm afraid I completely forgot to mention something potentially significant.
I have two computers which are both connected to a KVM switch. When I boot them up my Windows (music production) box is connected to the first KVM connection, and my Ubuntu machine is connected to the second connection). When the first machine is powered on the KVM "wakes up" and defaults to using connection 1 and I then manually switch to machine 2 when I wish to use it. As I said in my original bug report since I manually edited xorg.conf (probably back at about 5.04) X has worked perfectly on this system. It has only been broken since Gutsy. Following investigations it would appear that when the Ubuntu box is powered up with the focus on KVM connection 2 it starts X using a refresh rate of 76 Hz (instead of 85 Hz) However when it is powered up either with the monitor powered off or with the "KVM focus" on connection 1 (the Windows machine) X is started using a refresh rate of 50hz (which to all intents and purposes makes the monitor unusable - it feels like it's strobing) After further investigation I have also been able to get a second system not to detect the it's monitor properly by not having the monitor switched on during boot up. In this case its my crappy old 200Mhz machine which is currently attached to a dying 15" monitor. If I start the machine with the monitor connected it gets [EMAIL PROTECTED] whereas with the monitor attached it gets a more usable [EMAIL PROTECTED] Admittedly though this system is very old and the monitor is on its last legs anyway (vertical hold intermittently gives up) so this might not be a valid test. Even so this tends to suggest that when X is starting it is probing the monitor and is ignoring the values set up in xorg.conf. I would suggest this is incorrect behaviour. The X server should use the values in xorg conf and should only attempt to autodetect monitor characteristics either: 1 During initial install or 2 When the user requests it (either via the "Screen Resolution" dialogue, when the "Ctrl+Alt+Backspace" X server "panic" keys have been pressed etc.) Once xorg.conf is set up properly the X server should respect the values entered in there (especially if they have been hand edited) Currently getting a 50Hz refresh rate on my monitor has made my Ubuntu desktop unusable so it is now basically only ever powered up once a week (or so) to run Update Manager in the vain hope that this will have been fixed. Having become used to using it on a daily basis this is dissapointing to say the least. Still, thanks to Samba it at least it makes a good file server :) -- Cannot set correct monitor resolution for Iiyama Vision Master Pro 455 using displayconfig-gtk https://bugs.launchpad.net/bugs/158002 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
