Summary: ATI radeon M7 causes unusable video if switching between
X and vt
Product: DRI
Version: XOrg CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DRM modules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I've noticed that after a suspend to ram or disk
I can't switch between X and vt
if I suspend on vt, on resume switching to X causes hags on video ( I still can
use ssh not connect thru net)
if I suspend on X, on resmue X works but if I switch on vt and then back to X
I've the same effect as above...
I watched some code and I've found a possible solution:
on radeon_cp.c around line 1343
radeon_do_engine_reset( dev );
/* this let a DRI X server to work */
+ radeon_acknowledge_irqs( dev_priv );
+ radeon_do_cp_start( dev_priv );
+ radeon_emit_irq( dev );
DRM_DEBUG("radeon_do_resume_cp() complete\n");
and this let X work fine...
