I added maverick-proposed and tried linux-image-2.6.35-903-omap4 version 2.6.35-903.20 on a Panda. It works fine, I can run Unity on a 1080p monitor with no issue (i.e. no black screen). Note that the black screen can still be obtained on purpose with 'x11perf -copywinwin500' even under the recovery console, though. In which case you need to do a CTRL-ALT-F1 / ALT-F8 switch to get the display back.

Accepted linux-ti-omap4 into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here.

[Bug 653002] Re: omapdss DISPC error: GFX_FIFO_UNDERFLOW, disabling GFX
SRU Justification: Impact: While using SGX acceleration on Pandaboard, it's quite normal to face the GFX_FIFO_UNDERFLOW issue, that disable the display entirely. The only way to get the screen back to work is to reset it, or by changing to a text mode session and then getting back to X11. This issue makes practically impossible to use and stress the SGX driver on a Full HD monitor. Fix: While TI still didn't provide a proper way to fix is, a valid workaround was proposed to use the writeback buffers for GFX. The proposed patches are all already applied at Natty's branch, and this is basically a backport of them for Maverick. Testcase: Just run Unity using the SGX driver on a Full HD monitor, and try to use it normally, and your screen will probably get black with the following message at your dmesg: [ 404.169006] omapdss DISPC error: GFX_FIFO_UNDERFLOW, disabling GFX After applying these patches, you should be able to normally use Unity, without heading into any underflow issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/653002 Title: omapdss DISPC error: GFX_FIFO_UNDERFLOW, disabling GFX -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
