Hi, the FC4 Setup in graphical mode on this machine: [root@ghim ~]# cat /proc/cpuinfo | egrep '(vendor_id|model|cpu MHz)' vendor_id : GenuineIntel model : 2 model name : Intel(R) Pentium(R) 4 CPU 2.00GHz cpu MHz : 2000.572 [root@ghim ~]# lspci 00:00.0 Host bridge: VIA Technologies, Inc.

MGA G550 AGP (rev 01) [root@ghim ~]# Does Not work. I must reboot the system 4 or 5 times without turning off the PC just to see a clear graphic interface. The "linux nofb" option passed on boot sequence does not solve the problem. As soon as the setup process is finished I reboot the system and there's a bad X graphic interface, so the o.s. is unusable. After 4 or 6 reboots the graphic interface is loaded correctly and the system work great. I have found on bugzilla for FC4test[23] this Bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=153729 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=157556 Is this a known error for FC4 ? there is a bypass or a solution? Many thanks. -- Dario Lesca <d.lesca@xxxxxxxxxx>
