if you are running always the same XF86 version on both of your kernels then in theory it should always work. truth is that there is a secondary device on all Radeon adapters that is not needed for X11 - therefore having uninitialized adapters in the system should be ignored by X11 startup. as you do see a difference ( EE instead of WW) i would suggest you to look after X11 sources. (the error is expected not to be in the fglrx drivers!). but to my best knowledge there must be something else that makes the X11 startup fail - maybe its missing support for AGP. you may want to provide more information from your X11 log file. -Alex. ----- Original Message ----- From: "Roberto Sanchez" <rcsanchez97@xxxxxxxx> To: "XFree86-users" <xfree86@xxxxxxxxxxx> Sent: Wednesday, December 31, 2003 4:04 AM Subject: Problems with fglrx driver and kernel 2.6 I am currently running 2.6.0-mm2, [...] My card is a Radeon 9000 Pro, and I am running X4.3 on Debian unstable. The driver (version 3.7.0, released on 12-29-2003) builds fine against the 2.6 kernel, but when X starts I receive this error: (WW) fglrx: No matching Device section for instance (BusID PCI:2:0:1) found The strange part is that under 2.6.0, this error is fatal and causes the X server to fail to start. Under 2.4.23, the error message appears in the XFree68.log, but it is not fatal. I have Googled around for quite some time now and cannot find this specific problem mentioned anywhere. There is much discussion about the error message, but not this situation where it works in 2.4 and not in 2.6. Any ideas? -Roberto _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
