Subject: [PATCH] modesetting: Fix 16 bit depth/bpp mode
|
|
|
|
When setting DefaultDepth to 16 in the Screen section, the current
|
|
code requests a 32 bpp framebuffer, however the X-Server seems to
|
|
assumes 16 bpp.
|
|
|
|
Fixes commit 21217d02168d ("modesetting: Implement 32->24 bpp
|
|
conversion in shadow update")
|
|
