[Bug 753971] Re: Display garbled when connecting external displays
Hi Rogan, I understand your frustration with the bug process and am sorry that it seems arbitrary and possibly unfair to you. However I'd like to ask for your understanding too, in that the Ubuntu project has limited resources, and the process is in place to make sure those resources are used as efficiently as possible. Thus rather than trying to keep track of all the people still having display related problems that *sound* similar to this one in this report, which is cumbersome, it would really help if, once verified that this fix doesn't help your (and others') particular problem, you could file a separate report, this enables bug triagers to work more efficiently (keep in mind most triagers are volunteers), and developers to better target and try to solve bugs that are more focused. This is also the reason why we ask that you, the users, file the bug reports, instead of having a developer or triager trying to spin off all the remaining bugs, which would require creating them, subscribing each affected person, and then asking them to provide information via the apport tool. If you'd be kind enough to create the report yourself running apport (something the triager will ask for anyway), you'd be helping streamline the process, and it would be a great help to the project as a whole. From reading your description, your issues sound more driver or kernel- related than Unity-related (which is what this bug was about). Thus, it would really be more helpful if you would create a new report, which will contain hardware-specific information (that's one thing about *this* bug: it was NOT hardware-specific, I tested it on a lot of systems from different makes and models, that's why it was filed with such a broad list of machines, and eventually fixed exclusively in Unity). When you do that, I suggest you mention, in your report's description, that you've followed progress on this bug (give the number) and the posted solution didn't work for you. Then the triager will be sure to *not* close it as a dupe of this one. I can assure you that triagers *do* read the bug reports and we won't just summarily dismiss it because it sounds somewhat similar to something else. Thanks for your understanding and please let me know if you have other concerns. --- Daniel Manrique Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled when connecting external displays To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/753971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 753971] Re: Display garbled when connecting external displays
Rogan (and anyone else having this problem): Just to follow up on what Daniel said, the best thing to do will be to: 1.) Run 'lspci | grep VGA' in the terminal and note it's result 2.) Run 'ubuntu-bug unity' - make sure to tell the bug reporting wizard the problem is graphical 3.) In the summary of the bug put '[output of lspci | grep VGA] Display garbled when connecting external display' 4.) In the description make a note of what happens *exactly*. Try and include a screenshot (PrntScn key) if you can - and state that you have all updates (the triager should see this anyway) and that you looked at this bug but it didn't fix your problem. I can assure you your bug is not going to be rejected or marked as a duplicate if you follow these steps UNLESS someone else with the *exact* same video card has reported a bug with the same description. --- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled when connecting external displays To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/753971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 753971] Re: Display garbled when connecting external displays
We're getting mixed signals from users. Some users are running custom code, some aren't, there are many different hardware combinations and combinations of compiz and unity packages at play here, some people are saying that they get this issue, some aren't. What David is trying to say here is that people reporting the same bug and over and over is confusing internally and messing up our priorities. DX is accountable to a huge number of groups and we need to have a straight story here. This is especially the case with this one, where we're tracking what seems to be a number of larger issues manifesting with the same symptoms - it becomes very difficult to track what's helping and what's not on one single bug report where some people are saying fixed and others are saying not fixed. This has run on effects, such as fixes that might be helping one of the core problems that is manifesting as this issue being reverted because we think that it isn't working because some people are saying that it isn't fixed because there are still unrelated underlying issues manifesting in the same symptoms.

Sam, that's all well and good (and an inherent part of software development...), however; If you folks feel the need to close the bug for internal bookkeeping / organization / spring cleaning / warm fuzzies / whatever-you-want, then it would be damned spiffy if you could also take a moment to spin off some other bugs for the similar issues that are reported here that have not been fixed. It's sure not clear to me that the issues I'm having are unrelated to the screen corruption problems that have been reported as fixed, so if I go create a bug it's likely to be closed as a duplicate of this one, since I don't know how my problems are different. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled when connecting external displays To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/753971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Based on #62, I will mark this bug closed. The certification issue is resolved and the rest of the issues will be tracked in separate bugs, mostly driver related problems that are outside of the Unity scope. For reporters of other problems, or people suggesting adding suspend/hibernate cycles in the test case, I recommend tracking these long term reliability issues separately as well. Not all of that is Unity specific and it's becoming increasingly difficult to track the various threads in this report. Besides, I want a clear signal in this bug that DX and Jay solved the original problem for good.

I'll second Ben Romer's observation. It seems to have gotten better, but it's a long way from smooth functioning. I hope I won't come across as unhelpful (by not providing specific details), but a testing routine should be pretty simple: * Plug unplug the external monitor make sure everything still works * Suspend then wake up with the external monitor plugged in make sure everything still works * Restart the Ubuntu system with the external monitor plugged in make sure everything still works * Suspend then wake up with the laptop lid closed the external monitor plugged in make sure everything still works * Restart the Ubuntu system with the external monitor plugged in the lid laptop closed make sure everything still works * In the above points, try opening the lid when the system is running (if it was closed) Currently, all of the above points will cause major problems, sometimes to the point of requiring a reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled when connecting external displays To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/753971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Updated today and this seems to have *partially* fixed my screen corruption problem.

Same behavior as described in #66.
Besides I could not set primary display via the Monitor Preferences. I tried to
order the monitors in every way but unity dock is staying on the the laptop lcd.
In some configuration the external monitor is having corrupted screen - color
is invalid or monitor show a message resolution is not supported but the
resolution and refresh rate are set properly
And even if my laptop lcd - LVDS1 - is closed - during startup or
closing later - X is always starting on the internal lcd. I see that
xrandr can see LVSD1 as connected even if the display is closed.
With xrand commands the config can be correct.
I can execute the following in my case and then everything is fine:
#
#!/bin/bash
off=$(xrandr|grep \ connected|grep LVDS1|head -1|awk '{print $1}')
output=$(xrandr|grep \ connected|grep -v LVDS1|head -1|awk '{print $1}')
if [ -n $output ]
then
xrandr --output $output --primary
if [ -n $off ]
then
xrandr --output $off --off

You can add Asus EeePC 1001 to the list. Plugging in an external monitor creates either (a) a secondary monitor displaying only a top panel, (b) a secondary monitor displaying nothing with blocks of black on the primary (netbook) screen. Changing resolution makes no difference. Having the external monitor plugged in at login makes no difference. Acheiving result (a) or result (b) appears to be independent of operator behavior, i.e., it is random. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled when connecting external displays To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/753971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 753971] Re: Display garbled when connecting external displays
Might be useful to throw in some hibernate/resume test cases. I installed 3.8.16 on my Inspiron 1545. Based on my impressions so far I am afraid I will probably be bumping back down to 3.8.10 in the near future. I have from time to time had the screen remain completely black on resume. I can switch to a virtual terminal, log in, and run sudo service restart gdm and then I get noise as if gdm is restarting but the screen remains black. That behavior was occasional with 3.8.10 and may have something to do with resuming with the external monitor in a different plugged/unplugged state from when the system entered hibernation. However on 3.8.16 I could see the screen blanking out the same why while hibernation was starting... and it resumed to that unhappy state. So far it's just one data point but I am not encouraged.

I'll update shortly with a list of affected - systems. - - Install the update in -proposed: - - check the issue is fixed on intel/ATI - - Affected systems include: - - Sony VGN-Z540 - Dell Inspiron 1545 - Dell Vostro 3300 - Dell Vostro 3500 - Dell Vostro 3700 (2 affected systems) - Dell Latitude 2110 - Dell Latitude 13 - Dell Vostro 3400 - Dell Vostro V13 (2 affected systems) - Toshiba Tecra R700 - HP ProBook 6550b - Toshiba Tecra R850 (Intel) - Toshiba Tecra R850 (ATI) - Acer Aspire One - Dell Mini 10 - Lenovo Thinkpad T420s - Lenovo Thinkpad x220s - - ProblemType: Bug - DistroRelease: Ubuntu 11.04 - Package: xorg 1:7.6+4ubuntu3 - ProcVersionSignature: Ubuntu 2.6.38-8.41-generic 2.6.38.2 - Uname: Linux 2.6.38-8-generic i686 - Architecture: i386 - CompizPlugins: [core,bailer,detection,composite,opengl,decor,mousepoll,vpswitch,regex,animation,snap,expo,move,compiztoolbox,place,grid,imgpng,gnomecompat,wall,ezoom,workarounds,staticswitcher,resize,fade,unitymtgrabhandles,scale,session,unityshell] - CompositorRunning: compiz - DRM.card0.LVDS.1: - status: connected - enabled: enabled - dpms: On - modes: 1366x768 1280x720 1152x768 1024x768 800x600 848x480 720x480 640x480 - edid-base64: AP///wAOFL8UACUTAQOAIhN4Ck5NnldUkSYPUFQBAQEBAQEBAQEBAQEBAQEBeB1WwlAAJjA7J1oAWMEQAAAaeB1WwlAAJjA7J1oAWMEQAAAa/gBHNTI2SoAxNTZXQTEgAAAMEhcePWeg/wEBCiAgAIk= - DRM.card0.VGA.1: - status: disconnected - enabled: disabled - dpms: Off - modes: - edid-base64: - Date: Thu Apr 7 15:13:05 2011 - DistUpgraded: Fresh install - DistroCodename: natty - DistroVariant: ubuntu - GraphicsCard: - ATI Technologies Inc M92 LP [Mobility Radeon HD 4300 Series] [1002:9552] (prog-if 00 [VGA controller]) - Subsystem: Dell Device [1028:02aa] - InstallationMedia: Ubuntu 11.04 Natty Narwhal - Beta i386 (20110330) - MachineType: Dell Inc.
