Subject: can't start mir natively - 13.04

Hi,

I have managed to successfully build mir on my amd64 13.04 and wanted to
play a bit with the demo server (*Running Mir natively*
http://unity.ubuntu.com/mir/using_mir_on_pc.html) but ended up with a black
screen.

I am aware that patched drivers are needed to run X inside Mir but are
those needed to run it correctly next to a regular X (in a separate VT)? I
use the xorg-edgers version of xserver-xorg-video-ati drivers and use the
following command line:
# mir_demo_server --glog --glog-log-dir /home/darek/logs --vt 1
--glog-stderrthreshold 0 --display-report log --input-report log
--msg-processor-report log --session-mediator-report log --glog-minloglevel
0

This ends up with a black screen (my display eventually goes to sleep after
a couple of seconds).

In the logs dir there was only a single file and it seem to freeze right
after starting: http://pastebin.com/bX8z0R6U
I was unable to switch VTs (even to my default X session Ctrl+Alt+7).
After logging in via ssh from a different machine I did not see
mir_demo_server among the running processes.

I would appreciate any help with this issue and any hints for a mir-hacker
wannabe :)

Thanks,
Darek

Hi Dariusz,

You should only need Mir to run it beside another X session. You do not
need any of the driver changes which are only required for XMir.

When run successfully, you only see a black screen. You need to run a
client to see anything.

Though, it sounds like you can't VT switch and the Mir server has failed
(as not showing after a ssh in). If it has crashed I'd recommend checking
for a core dump. Core dumps are disabled by default, enable them by running
'ulimit -c unlimited' before running Mir.

If you continue to have problems, file a bug on
https://bugs.launchpad.net/mir/+filebug. Make sure to indicate what
hardware you have (from lspci)

I should clarify:

Once the Mir server is running correctly, you will need the changes to mesa
to run an accelerated client (i.e. most clients that you would be
interested in).
