Description CrystalCowboy 2005-01-27 14:19:18 UTC
With "radeon" driver and radeon 92xx card in AGP slot, display shows colorful
but uninterpretible stripes or other artifacts reminiscent of sync failure, when
X starts. Mobo is Soltek SL-B7C-FGR with KM400A Northbridge and integrated
Unichrome graphics. I have tried Radeon 9200 and 9250 cards in tha AGP slot.
With radeon driver, problem is as described. Graphics cards test fine with
radeon driver on other mobos. I have switched to the "vesa" driver, which works.
I have seen this problem with all versions of x.org under Fedora Core 2 and Core
3, with several 1024x768 or 1280x1024 LCD monitors. Most recent version of xorg
tested is xorg-x11-6.8.1-12.FC3.21 under FC3.
Comment 1 Alex Deucher 2005-01-28 15:30:19 UTC
what type of monitor ae you trying to use?  DVI? crt?  you may need to force the
type using the monitorlayout option. see bug 1559

Problem occurs with both VGA HD15 monitor attachment and DVI monitor attachment.
Other than changing Driver "radeon" to "vesa", no other changes are needed to
get X working. Hsync, Vsync etc. are set correctly. I will look into monitorlayout.

MonitorLayout has no effect.

The log shows that you are using two displays.  Which display works and which
one doesn't.  Please give more details about these monitors.

The log is wrong. I am using only one monitor, correctly defined in the
xorg.conf file as a NED LCD71V (typical 1280x1024 LCD with DVI and HD15
connectors). Note that the log file with the VESA driver shows no indication of
a second monitor.

See #1559.
Comment 7 Erik Andren 2006-04-02 18:42:29 UTC
Whats the status of this bug using a current version of xorg / radeon driver?

Comment 9 CrystalCowboy 2006-05-11 02:17:11 UTC
I have Fedora Core 5 installed now with the latest updates as of this morning
(2006-05-10). kernel 2.6.16-1.2111_FC5, xorg-x11-drivers-7.0-2. I currently have
a  monitor hooked up to the VGA (HD15) port.

The problem persists. When I set the driver in /etc/X11/xorg.conf to be
"radeon", on the next start of X the screen comes up black.

The latest /var/log/Xorg.0.log is at:
http://staff.chess.cornell.edu/~schuller/060510_xlog

The end of "dmesg" output is:
ACPI: PCI Interrupt 0000:01:00.0[A] -> GSI 16 (level, low) -> IRQ 21

current xorg.conf file which produced the above:
http://staff.chess.cornell.edu/~schuller/060510_xorg.conf

I am still operating with the vesa driver.

I went into the BIOS and switched it from "AGP 8X" to "AGP 4X" and now it works
with the radeon driver.
Comment 12 CrystalCowboy 2006-05-20 05:43:23 UTC
I have three of these machines. The one with FC5 and a second one with FC4
(kernel 2.6.16-1.2096_FC4,  xorg-x11 6.8.2-37) both work unconditionally, with
either a VGA or a DVI monitor connection.

A third machine, with FC4 (kernel 2.6.12-1.1398_FC4, updated to
xorg-x11-6.8.2-37.FC4.49.2.1) , works for VGA but not with DVI. I can live with
this, and can write it off as a bad card.

thanks.
