Xorg crash with ati rv740 (HD 4770) when kms/modeset enabler

[[e-mail]]

Binary package hint: xorg

It's impossible to get to the user interface when radeon.modeset=1, this means kms is still broken with rv740. Unless you know a little about it you will think ubuntu doesn't work, like this since kms is enable by default. So there is the 'xorg' problem which I hope it will be solve one day and the distribution 'ubuntu' problem, is it not possible to fallback to ums when the card is known to not be supported by kms as the rv740 : will improve the end-user experience, I know you care about it.

I 've tried the 2.6.34 kernel and it works with it. So it's a 2.6.35 bug ?

Seems like described in:
http://lkml.org/lkml/2010/7/22/596
but I haven't enough expertise.

SOLVED.

After looking everywhere I did try:
pci=nomsi
which solved all my problems, was having them sice a loong time.

My motherboard is 4coredual-sata-R.02 whith a PCIE graphic card.

Hey <email address hidden>,

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.

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.
