a6vision - This bug has been mostly fixed in Precise - see above for a couple of related bugs which are probably best addressed in separate, new bug reports.

I can confirm that setting consoleblank=0 stops the screen from becoming unresponsive. I set the consoleblank parameter in grub and left the computer for 30 minutes. After coming back to it, the console login screen was still visible and I could interact with the computer as normal. This suggests that the problem on this new kernel from proposed repo is now with DPMS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943263 Title: PC display will not turn on with Llano APUs connected to the VGA port To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/943263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 943263] Re: PC display will not turn on with Llano APUs connected to the VGA port
It appears that the bug is not entirely fixed. If I leave the computer for a while and come back to it, the screen is now blank and unresponsive, while the numlock/capslock keys on the keyboard still toggle so I'm guessing it's only the display that is still not working. If I then force-reboot the pc (Alt+SysRq+REISUB) then the display re- appears, but then disappears after leaving it again for a short while. I haven't waited around to see how long it takes for the screen to become unresponsive, but my guess would be after the display is put to sleep by power management stuff in the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943263 Title: PC display will not turn on with Llano APUs connected to the VGA port To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/943263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Thomas - Thanks for your feedback - the upstream kernel developers did add the following comment to this patch: radeon: initial fix for VGA on LLano system, 3 or 4 of us have spent time debugging this, and Jerome finally figured out the magic bit the BIOS/fglrx set that we didn't.

[Bug 943263] Re: PC display will not turn on with Llano APUs connected to the VGA port
I tried the new Ubuntu 12.04 LTS with kernel 3.4-rc5 with different monitor-configurations. When only a VGA connected monitor is used, everything works fine. The monitor doesn't go to power save after booting. This kernel seems to solve the problem of this bugreport. But when I connect two monitors, one on the HDMI- and one on the VGA- Interface at boottime only the monitor connected to HDMI works. I can't activate the monitor on VGA-interface. The monitor an VGA-monitor stays in power save. Then I tried an other idea: When I connect the monitor on the VGA- interface at boottime the monitor works correct like descripted above, and afterwards I connect the second monitor with the HDMI-interface, both monitors works fine and show the same content (mirrored screens). Then I want to expand the display to both monitors (two independent screens). A strange effect appears: Depending on the Screen for the starter-band, the mouse can only move on one of the monitors. I can move windows from one monitor to the other monitor, but I can't get them back, because of the limitation of the mousepointer. That's amazing. I appended the dmesg-file for the case with two monitors connected via VGA and HDMI at boottime. ** Attachment added: dmesg-file with kernel 3.4rc5 and two monitors https://bugs.launchpad.net/ubuntu/+source/linux/+bug/943263/+attachment/3134008/+files/dmesg.2012-05-06-18-27 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943263 Title: PC display will not turn on with Llano APUs connected to the VGA port To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/943263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can you help us to test the latest mainline kernel to verify whether it's already fixed in upstream? You can do that by following these steps: 1. Install 12.04 daily build or beta 2. Download the latest mainline kernel packages from http://kernel.ubuntu.com/~kernel-ppa/mainline/, by the time of this writing, the latest is v3.3-rc6 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc6-precise/), remember to choose the correct kernel flavour (i386, i386-pae or amd64) 3. Install them by running 'sudo dpkg -i downloaded packages' 4. Reboot and test VGA output Thanks! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943263 Title: PC display will not turn on with Llano APUs connected to the VGA port To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/943263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It may also help to enable drm debug messages before testing the kernel: Run 'sudo xdiagnose', then tick the first checkbox, apply, wait for grub to rebuild, then reboot the machine, reproduce the issue, and collect /var/log/dmesg. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943263 Title: PC display will not turn on with Llano APUs connected to the VGA port To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/943263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Anthony Wong: can't help with that, as it fails at step 1.: can not install 12.04 as the screen turns off after GRUB. --- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943263 Title: PC display will not turn on with Llano APUs connected to the VGA port To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/943263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
