Description Alan Grimes 2005-07-21 07:28:57 UTC 
Causes dmesg trash too.

I *can* use *either* card alone but not BOTH. 

I think both my r128 and mach64 kernel modules are trying to use /dev/drm/card0
and that is causing confusion. 

there might be an options switch for this somewhere but it's not documented... 

The drm.ko should automaticly assign a unique ./drm/card[N] for each device. 

Secondary to this is that my test application (which I am trying to debug)
displays markedly different color blending charactoristics on the two cards! 

I need to know which behavior is correct! =P

blaming this on the mach64 drm for now.

Do you still experience this issue with newer drivers ?
Please check the status of your issue.

Hi,

Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org.

To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default).

Sorry about the noise!
