The error is***: radeon 0000:05:00.0: Invalic PCI ROM header signature: exper600_cp: Failed to load firmware "radeon/JUNIPER_pfp.bin" [drm:0xffffffffa024bab3]. Fatal error during CPU init.*** I believe the video card is ATI Radeon 9600. Not sure if there is a .tcz for this. I have some interest in using the no machine server and read of someone successfully installing the client side under /usr. It has the ability to adjust to your client side resolution which seems to be the issue I am having with x11vnc.
