I attempted to work on this today, however I got to step 4 ("Switch to command line interface (CTRL+ALT+F1)") and was unable to get to a CLI prompt. I wait until X fails, the screen goes blank, and after making sure the system is no longer doing anything, I hit CTRL+ALT+F1. Nothing happens, and I am forced to do a hard reset.

Little advise for all who will work on closed video drivers (was "Closed video drivers for -realtime kernels")
Hi Brian, 2010/10/14 Brian David : [...] > Alessio, here is a link to the requested log files: > http://www.sunmachine.coop/ubuntu/xorg_logs.zip > Apologies for taking so long to get these to you. Don't worry! :-) The /var/log/Xorg.[0-9]*.log and dmesg output are mandatory for help to understand problems under all kernels. The former it is particularly X oriented when the latter is more generic (it is cover all things controlled by kernel). These simple text files (ASCII) are generated from a running system so they are specific of the software used to bootstrap the same system. So if you boot a -generic kernel these files will contain information about that kernel and not others. Other simple text files (ASCII) like configuration files are valid for all kernels because almost ever they are per-machine thus indifferently on which kernel you use to bootstrap or if you choose to change kernel at boot time through boot menu (aka GRUB). As you can see files in first lines often contains that information: [Line 5 cut from your Xorg.0.log] Current Operating System: Linux happy-cat 2.6.32-25-generic #44-Ubuntu SMP Fri Sep 17 20:26:08 UTC 2010 i686 FYI Also dmesg output contains the information of the kernel in execution when the output was generated: [Line 3 from my machine at work] [0.00] Linux version 2.6.32-25-generic (bui...@rothera) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #44-Ubuntu SMP Fri Sep 17 20:26:08 UTC 2010 (Ubuntu 2.6.32-25.44-generic 2.6.32.21+drm33.7) Both files you have sent me contains information about -generic kernel. Also if generally it is very useful have these files of a failing kernel and of a working one (to let use compare) in this case we can't proceed because outputs refers on the same kernel. Probably you are wondering how obtain these files if you can't access to GNOME working system (perhaps because -realtime kernel don't yet working with your video driver). It is fairly simple: 1) Start the system 2) Waiting that X fail (I don't like failsafe interface) 3) Be sure that system have done all necessary works (seeing the hard-disk led for example) 4) Switch to command line interface (CTRL+ALT+F1) 6) Authenticate yourself with the same username and password which you usually use for a working graphical system 5) Grab the requested files dmesg > dmesg.output.realtime cp /var/log/Xorg.0.log ./Xorg.0.log.realtime 6) reboot (and choose a working kernel!) 7) Sent files So I'm waiting for the right logs a little further :-) Ciao, Alessio -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
