I also wish to have framebuffer support whilst XEN is running. I can do that with an IBM Thinkcentre with this video: 21:16 [summer@numbat ~]$ lspci -v -s 00:02.0 00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02) (prog-if 00 [VGA]) Subsystem: IBM Unknown device 0285 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f0000000 (32-bit, prefetchable) [size=128M] Memory at e8000000 (32-bit, non-prefetchable) [size=512K] I/O ports at 1800 [size=8] Capabilities: 21:17 [summer@numbat ~]$ I simply modprobe intelfb and all works well, despite nasturtiums cast on this list. I've noticed that intelfb does not support the graphics on my HP box: [summer@bobtail ~]$ lspci -v -s 00:02.0 00:02.0 VGA compatible controller: Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02) (prog-if 00 [VGA]) Subsystem: Hewlett-Packard Company Unknown device 2801 Flags: bus master, fast devsel, latency 0, IRQ 21 Memory at f0400000 (32-bit, non-prefetchable) [size=1M] Memory at e0000000 (64-bit, prefetchable) [size=256M] I/O ports at 1100 [size=8] Capabilities: [summer@bobtail ~]$ I don't know much at all about these things, but it seemed a fair bet that a '945G driver might work, so I did some hacking on intelfb and I've booted. The good news is that "modprobe intelfb" doesn't hang the system; the screen goes powersaving, which given the gas supply here (Thankyou Apache), is probably a good thing. fbset finds a framebuffer driver and all seems well, better than it should be:-) Except for the blank screen. Time to call for help I think. But first: http://sourceforge.net/mailarchive/forum.php?thread_name=4815EEB4.2060509%40frugalware.org&forum_name=linux-fbdev-devel says that intelfb isn't really being maintained, and that clever souls are working on a replacement. Now, that _was_ about six weeks ago. vesafb (which I discovered cannot be compiled as a module) drives it fine with standard (not XEN) kernels. I have a similar system running F9 and it's fine _but_ it's so long since I had a working kernel-xen in Fedora that I don't recall whether I had XEN and framebuffer. Since I wish to run SL5, I really should stay with 2.6.18 kernels. Before I post the copious kernel messages I have and the patch for others' perusal, what does the list recommend? ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
