Bug Description

Binary package hint: xorg

Since the libdrm fix (619663?) was downloaded to my laptop yesterday, I switched my monitor config from top/bottom to side-by-side. It appears that if I have the secondary display enabled, I now end up with corrupted text in emacs, my primary editor. I can reproduce the corrupted text when I do a mouse selection (as shown in the pictures I will attach). I can also see corrupted text when I type, or when I paste text into the buffer. If I disable the second monitor, I can't reproduce the problem.

I haven't seen the problem in other applications yet, so maybe this is an emacs issue instead.

I should note some further observations:
First of all, see the word "software" in the second line for the 'Mouse selection' picture. This example is actually quite tame. I really can't see what I'm typing properly most of the time. In fact, the last line in the picture (should be the same as the line above it) attached to this comment is the norm.

When I press enter, or when I do things that appear to cause a redraw, normal text returns.

I've seen blinking, outlined, and bold text appear, and not directly under the cursor while typing. Underscores have ended up in odd places.

I did test putting my secondary monitor under my laptop monitor, and I could not reproduce the problem. This also makes me think that this is related to the libdrm framebuffer fixes that came in this week.

Hey David,

Thanks for your interest in Ubuntu.

Thanks for testing maverick during its development period. Unfortunately it looks like this bug report didn't get attention during the maverick development period. But I see there's not been more comments on the bug since the release, which makes me wonder if this is still an issue for you?

If you've not seen this issue since maverick's release yourself, it may have been solved by kernel or X or other updates that occurred late in the release; if so, would you mind please closing the bug for us? Go to the URL mentioned in this bug report, click the yellow icon(s) in the status column and set to 'Fix Released'.

If you no longer have the hardware needed to reproduce the problem, or otherwise feel the bug no longer needs tracked in Launchpad, you can set the status to 'Invalid'.

If you are the original reporter and still have this issue, just reply to this email saying so. (Or set the bug status to Confirmed.) If you are able to re-test this against 11.04 Natty Narwhal (our current development focus) and find the issue still affects Natty, please also run 'apport-collect <bug-number>' while running natty, which will add fresh logs and debug data, and flag it for the Ubuntu-X development team to look at.

Hi,

I'm sorry to say that the computer I had the issue with was just retired
last week. I did have the problem the whole time I had that computer, and I
did notice recently that there was another application where I could see a
sign of the problem, but I can't remember what it was. I gave up on this
bug because I could see that I was the only one who had any interest in it.

Thank you for asking about it.

-Dave

Since the hardware is no longer available for doing troubleshooting with, we'll have to close the bug for now. However please feel free to reopen if you or anyone else has the same HW and can reproduce this issue using the latest development version of Ubuntu and is willing to do some troubleshooting with it.

I just upgraded to Natty from Lucid and I am experiencing the same problem with emacs and second X server. I'm using nvidia drivers.

Sorry, I didn't read this bug fully. I'm actually having problems with focusing on the window, not with corrupted text.
