Corrupt Terminal Graphics

[picopir8]

I have two Ampro ETX 610 boards (http://www.ampro.com/Products/ETX%2DXTX/ETX%5F610/), one connected to a VGA CRT monitor, the other connected to an NEC SVA150XG05TB flat panel display. This bug ONLY applies to the one with the NEC flat panel, everything worked just fine on the one with the CRT monitor.

I successfully installed the CLI only (ie no xorg, window manager, etc.) using the Ubuntu 8.04 mini.iso. However, at bootup, the graphics would crash shortly after "Loading Hardware Drivers" is displayed. After several minutes, the sytem would crash and reboot. Note, usplash is NOT installed, boot status is purely text based.

As mentioned earlier, the problem does not exist on the system with the CRT monitor, so I moved the drive to that setup, and installed xorg, gdm, and fluxbox. I then replaced the card in the system with the NEC flat panel. The graphics still get corrupt at the same point, however the graphics return once gdm is loaded.

Changing to a virtual terminal causes the same viceo corruption to appear. The graphics return to normal once returned to the desktop. Also the same graphics corruption is seen when rebooting/shutting down (again, usplash is not installed, so shutdown should be text based).

No corruption is present within fluxbox terminal windows.

Just in case here is xorg.conf

... and Xorg.0.log

This video shows the video corruption at bootup. Note, shortly after "Loading Hardware Drivers" is displayed, the screen is corrupted and then returns once gdm/fluxbox is launched.

This video show switching from desktop to tty1 (causing video corruption), then back to desktop (resolving video corruption).

This sounds similar to Bug #42974, however that is two years old. I had also installed Ubuntu 7.04 on both of these systems and did not experience these problems with that version. Consequently either this bug reappeared or it is a new bug.

[picopir8 (sgreasby)]

The previously mentioned similar bug (42974) referenced Bug #40297, where the submitter tried booting using different values in the "vga=xxx" option.

I found that adding vga=773 to my boot options allows me to boot up w/o a corrupt screen.

Shortly after "Loading hardware drivers" is displayed, I see the following:

[ 110.212497] lxfb 0000:00:01.1: failed to map frame buffer or controller registers.

There hasn't been any recent activity in this bug report and we were wondering if this is still an issue? The Ubuntu kernel team is actively working on the upcoming Intrepid Ibex 8.10 release. If you could please test the latest Alpha release for Intrepid it would be much appreciated - http://www.ubuntu.com/testing . Please let us know your results. If the issue still exists, please also provide the appropriate debugging information as outlined at https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks in advance.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Sorry, I no longer have access to that hardware to perform the test (it was
the property of a former employer). However, I can tell you I did perform a
network install using the mini iso as late as about three/four weeks ago.
At that time (post 8.4.1 release) it still had a problem.

I did do a few internet searches on the matter and it appears the problem
may be fixed in more recent kernels. I found a few threads talking about
how support had been additional display frequencies. Aparently the display
adapter in the Geode was confused by some of these frequencies (it did not
support them but they were close enough to the ones it did support that it
thought they were supported). That code was then removed from subsequent
kernel builds as a solution until it could get worked out. IIRC, this all
took place around the first/second week of May.

Sorry for being so vague, but since I had the work around noted in the bug
report, I just moved forward with that. Also all my documentation was left
at my former employer. However, I am confident that kernels developed after
about May 15th will likely work w/o issue.

Hi picopir8,

Thanks for the update. I'll just go ahead and close this report since you no longer have access to the hardware. Thanks.
