[drm:radeon_dvi_detect] *ERROR* DVI-I-2: probed a monitor but no|invalid EDID

[Richard Eames]

Binary package hint: xserver-xorg-video-ati

One of the upgrades in the past few days has made my second monitor not work. Error description in dmesg log.
xrandr gives the following:

$ xrandr
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192
DVI-0 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 473mm x 296mm

DIN disconnected (normal left inverted right x axis y axis)

I tried unplugging the cables for the monitor, and reconnecting them, making sure they were in firmly, and still the same problem.

bryce, do you think Bug #601376 and Bug #539851 are the same issue? and maybe https://bugzilla.redhat.com/show_bug.cgi?id=533632

[Ilia (look256)]

Well, it looks like I'm affected by the same bug. But my xrandr shows the state of monitor cables correctly. But the second monitor goes to the safemode on booting ubuntu 10.04 and 10.10. it affected kernel 2.6.32 and 2.6.34 in 10.04. and bare installing 10.10

radeon x1600.

Hey Richard,

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.

[Ilia (look256)]

Well. I confirm? that it's still an issue for me. I'll check if it was solved by updates this week and describe it here. let's set 25.02.11 as a deadline :).

[Ilia (look256)]

I confirm that it's still an issue for me. DistroRelease: Ubuntu 10.10, Ubuntu 10.04. Last updates don't solved that issue. It looks like something connected with KMS.

This also affects my Toshiba L300D Laptop. Affects 11.04 Natty.

[madbiologist (me-again)]

The L300D problem should be solved in the latest kernels, namely 3.1 (upstream), 3.0.4 (upstream) and 3.0.0-10.16 (available in the Ubuntu 11.10 "Oneiric Ocelot" repositories). This fix was also cc'd to upstream's stable kernel series so it should be coming to Ubuntu 11.04 "Natty Narwhal" in a future SRU.

[madbiologist (me-again)]

If you want to try the L300D fix in the meantime, PPA's of the mainline kernels are available at http://kernel.ubuntu.com/~kernel-ppa/mainline/

[Bryce Harrington (bryce)]

Sounds like this got fixed in the kernel a while ago; since there's been no subsequent comments I'm going to assume the problem is resolved.

See also bug 992346 for the more general problem of invalid edid and working around it by installing an alternate EDID file.
