I have a similar problem: right after boot, my screen works (displays kernel messages) until maybe drm module is loaded (I guess by udev), then it becomes immediately blank and monitor is blinking, and then works again some time after fbcon and radeon modules are manually loaded in boot scripts (before starting X). It depends on modeset=1; if I use modeset=0 this behaviour doesn't appear, bua X cannot run without KMS. I have an AMD A4-3300 APU and using a (vanilla) linux kernel 3.5.3 (on Slackware64) The real problem is that some time (a couple of minutes or so) after video adapter is in idle mode (e.g. if I am not using the PC), monitor blinks (as in low power mode) screen is blank and system is no longer recoverable (unless I use e.g. ssh just to power it off). I don't know if the two problems are really related or not. Voltage problems? I have these messages in dmesg, too, when it happens: [ 2405.888198] [drm:radeon_atom_encoder_dpms], encoder dpms 33 to mode 0, devices 0001, active_devices 0001 [ 2405.892352] [drm:radeon_dp_get_link_status], link status 44 44 01 00 44 44 [ 2405.892360] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 0.4V pre_emph 3.5dB [ 2405.892365] [drm:dp_get_adjust_train], using signal parameters: voltage 0.4V pre_emph 3.5dB [ 2405.893921] [drm:radeon_dp_get_link_status], link status 44 44 01 00 48 44 [ 2405.893926] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 0.4V pre_emph 6dB [ 2405.893931] [drm:dp_get_adjust_train], using signal parameters: voltage 0.4V pre_emph 6dB [ 2405.895508] [drm:radeon_dp_get_link_status], link status 44 44 01 00 4c 44 [ 2405.895514] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 0.4V pre_emph 9.5dB [ 2405.895518] [drm:dp_get_adjust_train], using signal parameters: voltage 0.4V pre_emph 9.5dB [ 2405.897079] [drm:radeon_dp_get_link_status], link status 44 44 01 00 41 44 [ 2405.897085] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 0.6V pre_emph 0dB [ 2405.897089] [drm:dp_get_adjust_train], using signal parameters: voltage 0.6V pre_emph 0dB [ 2405.898632] [drm:radeon_dp_get_link_status], link status 44 44 01 00 45 44 [ 2405.898634] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 0.6V pre_emph 3.5dB [ 2405.898636] [drm:dp_get_adjust_train], using signal parameters: voltage 0.6V pre_emph 3.5dB [ 2405.900152] [drm:radeon_dp_get_link_status], link status 44 44 01 00 49 44 [ 2405.900155] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 0.6V pre_emph 6dB [ 2405.900156] [drm:dp_get_adjust_train], using signal parameters: voltage 0.6V pre_emph 6dB [ 2405.901674] [drm:radeon_dp_get_link_status], link status 44 44 01 00 42 44 [ 2405.901676] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 0.8V pre_emph 0dB [ 2405.901677] [drm:dp_get_adjust_train], using signal parameters: voltage 0.8V pre_emph 0dB [ 2405.903194] [drm:radeon_dp_get_link_status], link status 44 44 01 00 46 44 [ 2405.903196] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 0.8V pre_emph 3.5dB [ 2405.903197] [drm:dp_get_adjust_train], using signal parameters: voltage 0.8V pre_emph 3.5dB [ 2405.904715] [drm:radeon_dp_get_link_status], link status 44 44 01 00 43 44 [ 2405.904717] [drm:dp_get_adjust_train], requested signal parameters: lane 0 voltage 1.2V pre_emph 0dB [ 2405.904718] [drm:dp_get_adjust_train], using signal parameters: voltage 1.2V pre_emph 0dB [ 2405.906235] [drm:radeon_dp_get_link_status], link status 44 44 01 00 43 44 [ 2405.906238] [drm:radeon_dp_link_train_cr] *ERROR* clock recovery reached max voltage [ 2405.906240] [drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed -- 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

Created attachment 66808 dmesg booting with 2 monitors plugged drm.debug=4 This drm-fixes-3.6 branch just gives me two black screens when I have them both plugged during the boot. And when X starts I get a 100% processor usage from the X process and nothing displayed. The Xorg.0.log shows nothing out of the ordinary. But I think there is something really wrong because my X server never starts accepting connection from my login manager. When I boot with only the DVI screen plugged, no problem it boots fine. After having booted with only the DVI plugging the VGA one works just like before. When X puts my screens into DPMS off and I try to wake them up, the VGA goes back on correctly with this branch whereas it didn't with vanilla kernel. So there are some good points and some bad points. Attached is dmesg | grep -e drm -e radeon when both screens are connected, after X is started. -- 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

So the behavior is somewhat similar to the vanilla kernel in that regard. Booting with the VGA unplugged and plugging it later gives the same behavior as without that patch (i.e. better than the vanilla kernel).

Created attachment 66828 dmesg booting with 2 monitors plugged patch applyed on top of drm-fixes-3.6 drm.debug=4 (X with NoAccel) I tested a few things and found out that with the patch over drm- fixes-3.6 I generally get the DVI screen working but the VGA has no signal if it is plugged during the boot. The generally is there because sometimes I just get a black screen on the DVI and then X causes a GPU Hangup (The NoAccel suppresses the Hangup). This situation is rare and If the GPU hangup pressing the reset switch (instead of letting the machine off during some time and doing a cold boot) causes it to happen more often. A quick way to do it is booting without the patch starting X without NoAccel and then pressing the reset button and booting with the patch. Seems the firmware doesn't reset the state of the card properly during POST or something. Last night the problem happened by itself, so it might happen without trying to provoke it. This morning I tried rebooting a few times but didn't get it to happen without provoking it. The attachment is dmesg | grep -e drm -e radeon when the DVI screen stays black (VGA saying no signal) and without hangup (provoking it on the previous boot). The last part is X turning the screens off and trying to wake them up. The situation didn't change. -- 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

Oh yes there was and now even without the patch my machine displays something on the DVI screen when both screens are plugged and the GPU doesn't hang anymore even without NoAccel (but only from a cold boot, if I reboot/reset I get a black screen and the GPU hangup). So part of the problem was really a firmware issue. With the patch I can't seem to provoke the GPU hangup anymore. But my VGA screen continues to be stubbornly off when booting with both screens plugged. Continues to work if I plug my VGA screen after booting. So now I can start X safely without NoAccel that's one good thing. BTW my motherboad is an Asus F1A75-M now my firmware is the latest version (2004) upgraded from 1903.

BTW I've just one monitor on VGA port. The 1st problem (at boot, for about 30-40 seconds screen is blanking and monitor LED is blinking; after that, messages appear again in console, before starting X [init 3 mode]) seems to be still present, though.

Sorry, I've managed to resolve my first problem (screen blanking after boot for about 30-40 seconds): it is not related to drm, but it depends on fbcon loaded as a module (instead of it being compiled statically). As explained in /usr/src/linux/Documentation/fb/fbcon.txt if fbcon is compiled as a module (CONFIG_FRAMEBUFFER_CONSOLE=m) it can produce blanking and/or garbage on display if it is not loaded immediately. If Framebuffer Console support is compiled statically (CONFIG_FRAMEBUFFER_CONSOLE=y) there is no blanking here.

Oh fun. Seeing how the driver seems to mess up things (with your previous comment) with the connectors when booting with both plugged, I tried to boot without the nvidia card and both monitors plugged and the unplugging the VGA monitor during the boot (before X starts) and both screens when off, the VGA one with no connection and the DVI with no signal.

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

[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

[Bug 943263] Re: PC display will not turn on with Llano APUs connected to the VGA port
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.

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

[Bug 943263] [NEW] PC display will not turn on in Oneiric with Llano APUs connected to the VGA port
Public bug reported: The PC has a Llano A6-3650 APU with a display connected to the VGA port, but the display turns off when plymouth should appear, thus making installation from liveCD/USB impossible. Ubuntu starts up, as I can hear the login sound, but nothing is visible. Filed separately, as requested in bug #825777, as this one is about a PC, and the other one is about laptops. --- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: linux-image-3.0.0-16-generic-pae 3.0.0-16.28 ProcVersionSignature: Ubuntu 3.0.0-16.28-generic-pae 3.0.17 Uname: Linux 3.0.0-16-generic-pae i686 NonfreeKernelModules: fglrx AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
