black and white bar lines across both monitors on start up

[heather michel]

When i boot up my computer (before the purple ubuntu screen loads) I get black and white bar lines across both monitors. This has been a problem since I upgraded from karmic to lucid. I run it on a dell 410 XPS machine with two monitors looking at the same desktop. One monitor is a dell flat screen and the other is an acer flat screen monitor. There is an odd high pitched sound when it is showing the bars as well.. What is up? I have done all available updates at this time.

Have you tried booting Ubuntu with just one monitor attached? This may be worth a try to narrow down the source of the problem. See: https://wiki.ubuntu.com/X/MonitorDetection

Good luck.

If I turn on the machine with only one monitor attached I still get the black/white bars across the screen.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

This is still happening. Started in 10.4 and continued in 10.11. It happens even with just one monitor attached. I have a dell xps 410 with a Dell and an Acer monitors attached.

[heather michel (hmemichel)]

please if anyone could help me resolve this? It is still happening in linux ubuntu 2010-11, I don't have access to the 2011-4 update yet.

still happening in 11.10

It's probably a driver bug, but since you didn't include any config or log files it's not possible to do any analysis to narrow it down.

Please attach your /var/log/Xorg.0.log, /etc/X11/xorg.conf, ~/.config/monitors.xml and the output of `dmesg`. That should at least give us the basic run down of your system so we can determine what the next steps should be. If there's any way you can take a photo of the monitors showing the bars, that would help.

I assume after the boot is over, the oddness goes away?

[heather michel (hmemichel)]

here is the monitors.xml. Still looking for the other two files requested.

[heather michel (hmemichel)]

here is the xorg.0.log file

[heather michel (hmemichel)]

here is the xorg.conf

[heather michel (hmemichel)]

yes, once the system boots up all the way the oddness goes away.
