Wayland ?

[dboosalis]

Hi All.

I've been keeping up with my daily updates on my 12.4 prerelease. Today was no different, but what caught my eye was a wayland update. Anyone know how I can give wayland a go, as right now I am running AMD's Catalyist driver.

Hi...

I'm not sure if I completely understand your question. Do you mean as a replacement for the X server or for your graphics driver? If it's the former, I'm not sure if that's even possible at this time. If the latter, Wayland, from what I understand, it seems Wayland will not be compatible with proprietary drivers, such as Catalyst...

"Can Wayland be used with the closed source proprietary graphics drivers?

No, not at this time. fglrx, nvidia, psb, and other closed source drivers are developed externally to X.org and externally to Ubuntu. As far as we know, work to update them to conform to the new KMS/GEM/etc. architecture is not planned (at least, not publicly) and would need to be done before they could be used under Wayland.

According to Kristian closed drivers need 2 things:

A way to set the graphics mode (like KMS, but it could also be a standalone library)
A way to share video memory buffers (for example an EGLImage) between processes

psb already is capable of mode setting. I (adamw) don't know if it can share buffers."

Hope this helps...

Regards...

Sorry for not making my question clear. I wanted to know if I can run Wayland on my AMD hardware. You answered that for me because at this time I am unwilling to remove the Catalyist driver for the opensource version.

Thank 's for your reply
