[Bug 1024507] Re: 12.10 quantal boots to black screen on iMac
Still no resolution of this problem. I have used kernel 3.8.0 under ubuntu 13.04 and am now using kernel 3.7.9 under archlinux. Can boot both OK, using 'nomodeset'. But both still resume to the wrong screen. The log tells me that the kernel, when it starts to sleep, tries to save state with 'vbetool'. That shows an error, no card detected. On resume I suppose there is no info available to allow radeon module to set correct screen; it defaults to wrong video screen and all terminals are black. However, the terms do accept keyboard input. I believe this is a kernel module problem; not an xorg module problem. It affects terminals not running X (and those running X as well). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1024507 Title: 12.10 quantal boots to black screen on iMac To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1024507/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Problems still present on latest kernel, 3.5.0-16-generic. - nomodeset kernel param is necessary to get a boot screen. - xorg.conf must have Device as fbdev or get black screen when X starts. -- However, fbdev gives quite good enough performance for me. - Suspend works but resume is always to black screen (wrong display). -- this last means I cannot use suspend -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1024507 Title: 12.10 quantal boots to black screen on iMac To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1024507/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1024507] Re: 12.10 quantal boots to black screen on iMac
Results so far (using grub2, with manual edits to boot params to load these kernels): ### kernel 3.2.0-030200rc6-generic (16 Dec 2011) Used nomodeset as boot param. suspend from menu does not stop system - black screen with blinking cursor on vt1, white screen on vt7 until mouse click, then could use desktop. Network non-functional. ### kernel 3.4.0-030400-generic (22 May 2012) nomodeset at boot. supend from menu does not stop system - black screen. Press of space and get blinking cursor on vt1, desktop on vt7. Network down and not recoverable using menu. Could bring up wlan0 manually but wpa_supplicant command failed to run - no conf file - so abandoned attempt. Tried to suspend a second time. Nothing happened. dmesg reported '... gnome-control-c general protection ip:... error in libglib-2.0.so.0 ...' Suspect something due to upgrade of glibc since this kernel. ### kernel 3.5.0-030500rc1-generic (22 June 2012) nomodeset at boot. suspend from menu stops system. Screen goes black and disk stops. Press space and disk restarts. Screen stays black. Tried blind restart using shutdown command and using Ctl-Alt-Del. No response from either. Power button to restart. I think latest kernel can be restarted using Ctl-Alt-Del. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1024507 Title: 12.10 quantal boots to black screen on iMac To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1024507/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 1024507] Re: 12.10 quantal boots to black screen on iMac
I can do the testing you requested over the next few days. Can I suggest I start with kernels 3.2.0.10 vs 3.4, since I know that some time during kernel 3.2 development suspend/resume started working properly (see bug#863969, comment on 25 Jan 2012, kernel 3.2.0.10.10). Kernel 3.4.4, in archlinux at the moment, doesn't work, so it might be good to work backwards from there. Or to work forwards from early 3.2 kernels to see what happened to fix it? regards Peter Hayward On 16 July 2012 19:04, Joseph Salisbury joseph.salisb...@canonical.com wrote: I'd like to perform a kernel bisect to identify the commit that caused this regression.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.5kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages. Once you've tested the upstream kernel, please remove the 'needs- upstream-testing' tag(Only that one tag, please leave the other tags). 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 'needs- upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.

[Bug 1024507] Re: 12.10 quantal boots to black screen on iMac
It just happens I can do this now... Am running kernel 3.5.0-030500rc7-generic now but it behaves just like the other kernels I have tried. Earlier today I raised a kernel bug report #44851 at bugzilla.kernel.org - pointing at suspend/resume, but I think its the same thing. I will do the documentation you specified. ** Tags added: kernel-bug-exists-upstream ** Description changed: - Running 12.10, updated today, on iMac 11,2 (mid 2010) with AMD Radeon 4670. - Using kernel radeon driver (lsmod shows it running). + Running 12.10, updated today, on iMac 11,2 (mid 2010) with AMD Radeon 4670. + Using kernel radeon driver (lsmod shows it running). Normal boot results in black screen. Ctl-Alt-Del reboots; indicating that system did boot. If I place 'nomodeset' on kernel command line, main screen can be seen and unity desktop runs normally. This appears to be a regression in the kernel, similar to bug 597070 (ubuntu 11.04 - used fglrx to get video to work) and to bug 863969 (ubuntu 11.10 - where an upgrade to the 3.2 kernel seemed to improve video detection). Suspend and resume does not work either, not turning off the system, only the video, and resuming to a black screen. I think the problem is in KMS, because the black screen happens even if I boot into text mode and using nomodeset fixes it. Hence filing this against xorg but expect it to go to kernel developers.

The same behaviour is observed on my iMac system when I boot archlinux (kernel 3.4.4) on another partition. In that case I needed to set 'radeon mode=0' in the modules.conf file to allow me to see anything on the main screen, even text.
