| |
Hello All,
I have a two seat multiseat config using two gpus. when I first boot the computer and starts to work with seat 0, after a few minutes my screen goes black and it behaves like it went to sleep.
the system has two gpus, seat 1 uses an ati 5450HD at slot 1 (pcie2.0x16) and seat 0 uses an ati 3650HD at slot 1 (pciex4).
this only happens after cold reboot/power cycle, after I restart X, it doesn't happens again.
also this doesn't occurs on seat 1 so I suspect it has to do with the pci slot.
I've manually disabled DPMS in X but I don't think that is the issue.
I'm using kernel 3.1.1, my dmesg can be found at http://pastebin.com/TZHvDWNe and my lspci can be found at http://paste.pocoo.org/show/509652/
any ideas what can cause it?
Thanks
Eial.
