1002:6779 AMD RADEON HD 6450 random pixels on display

[Arseny Klimovsky]

I'm trying to use a AMD RADEON HD 6450 video card, but it fails to show a login screen, see screen photo attached.
I've tried different kernel (2.6.38-8, 2.6.38-10, 2.6.39-3) and driver versions (from main repository and from xorg-edgers ppa), no success.
The fglrx drivers makes a SegFault on my system. I tried to use vesa and removed packages, related to radeon, but it still does not show the login screen correctly, see the same screen photo.

The logs and info attached automatically are from the situation where a vesa driver expected to be used.

Just wanted to add that Dave Airlie sent me a patch{0] in the FreeDesktop Bug Tracker[1] for this same issue which fixed the problem for me.

Would be great to have this patch included for the oneiric kernel if possible, it would make Ubuntu work for people with HD6450 cards out of the box.

I haven't tried it myself, but looks promising. Moving over to the kernel, though it's not going to help oneiric since the kernel freeze is in effect (which means the kernel for the final installation image is already set in stone).

Arseny Klimovsky, thank you for reporting this and helping make Ubuntu better. Natty reached EOL on October 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:
needs-upstream-testing

This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

Please let us know your results. Thank you for your understanding.

[Po-Hsu Lin (cypressyew)]

Closing this bug with Won't fix as this kernel / release is no longer supported.
Please feel free to open a new bug report if you're still experiencing this on a newer release (Bionic 18.04.3 / Disco 19.04)
Thanks!
