Subject: [PATCH] [GLX/SWrast] Make GLX with SWrast enabled work on older Xservers.
|
||
|
|
Patch-mainline: To be upstreamed
|
||
|
|
|
||
|
|
Older Xservers don't offer a set of configs/visuals that is compatible
|
||
|
|
with DRI. If no visuals or configs are found let driswCreateScreen()
|
||
|
|
fail so that the next fallback path is take.
