[Bug 907381] Re: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected
Lee Willis - that's very nice to hear! Yeah, it would be interesting to know the actual issue, so I would also like the developers to further investigate it. If it were purely hardware error, the switching would occur in Windows (7 in my test case) too, but it doesn't. However, I am very glad that workaround solves the problem, so Vostro 3550 users can enjoy linux! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907381 Title: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/907381/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 907381] Re: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected
Some good news - I've now been running for 3 days solid with the xinput's disabled and have had absolutely NO resolution switches. So - where does this leave this bug - does that narrow down the actual issue? Is there something else I can do to generate further diagnostic information? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907381 Title: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/907381/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 907381] Re: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected
Hi Goran, Sorry for the delay replying. I've had a couple of chances to test and I too haven't seen any display switches with those inputs disabled. I will say though that I've only had chance to perform short tests (A couple of hours), so not sure it's conclusive, but certainly positive - thanks. I'll report more as I run a longer test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907381 Title: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/907381/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Lee Willis, have you had time to test if disabling Video Bus (2×) and Dell WMI hotkeys with xinput disable is working for you?

[Bug 907381] Re: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected
Lee Willis, I was having the very same issue with fglrx - corrupted display, barely usabe, clicking didn't work, even after barely possible to target what you wanted to click, etc. However, I came to this fix that works - run Terminal with keyboard CTRL+ALT+T and do sudo su and then xrandr --output VGA1 --auto --right-of LVDS1 --output VGA1 --auto --scale 1.0001x1.0001 After that, everything becomes usable again. However, this does NOT fix the issue with random switching of resolutions/monitors/mirroring! That is still present. Now, I am testing with Ubuntu 14.04 for my bug report and will provide feedback when I have used it for long enough. Oh, Christopher M. Penalver, I have seen your info that this laptop had new BIOS released - the A12 and I flashed it today. I still had the exact same problem on Ubuntu 13.10 (saucy) and as I said, I will report (in my bug report) how version 14.04 goes... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907381 Title: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/907381/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
