I have my university server on Sun Ultra 10 (444 Mhz na 256 mb ram).
I have lastest Debian installed here. Having linux has some pros and cons.
The pros are:
- newer packages
- easy to obtain overlay mode (to watching movies)
Cons:
- lack of SUN java and flash
I find ati rage 2 video faster and easy to handle than 13W3 so i dismount Creator 3d (ffb3) from it. Ati rage2 has only 3.5 mb vram so DRI doesn't work. Other graphics cards might work if there exists sun version of them (like permedia2). SCSI cards works better in linux than solaris. Ultra10 should support Solaris 10 but i have Sol 9 earlier too and i worked without problems.
