[rv635] blank screen and hangs radeon 3650 on amd64

if i set the xorg.conf to use VESA, GDM starts ok. if i set it to radeon then i get the freeze at a black screen

i have installed. i set the driver to radeon. (see attached xorg.conf).

now when X starts the whole computer reboots.

PS: there is no new log file write. or atleast it does not get flushed to disk before the reboot

Bug 252927 is about the same card, and is similar, grey vs black screen.

Sorry if this is not the place to post this, but i have the same problem but with an integrated intel video card (Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller) on a Vostro 1500, first parts of the progress bar are all over the place and then it goes blank even booting whit safe graphics mode.

Ok this is weird, if i use the default language and keyboard it boots ok, but if i choose spanish and latinamerican keyboard it goes blank.

Thanks for your report. Please take away "splash" from the boot parameters. Can you try to debug it remotely via ssh and get the log from the default configuration (no driver specified, should use "ati")?

Can you also please try the newest driver in intrepid and if it's still the same file a bug upstream on bugs.freedesktop.org (Product=xorg, Component=Driver/Radeon), attaching your Xorg.0.log?

i got the radeon update as of this morning.
i removed splash quiet and xforcevesa from the grub line (boot showed oldskool boot messages)
i commented out Driver from my xorg.conf
login over ssh
started GDM (i have remove the symlinks so that GDM did not start at boot)
screen goes blank. ssh session is unresponsive. wont respond to pings. caps lock key does not light caps LED.

when i reboot the Xorg.0.log is from earlier today when i started GDM with the vesa driver. so no log is written.

any ideas for further debugging?

Please try the device Option "DRI" "off". I would also suggest you try to start X using strace to see approximately how far it gets before it hangs:
 sudo strace Xorg
or
 sudo strace -o xorg.strace.log Xorg

You can also try to start it with gdb, setting breakpoints to narrow it down.

with the boot options as before, and DRI off, i get the same lockup.
(just to note the magic sysrq keys don't work)

when i reboot after straceing to a file, the file is not there (and its not in lost and found).

strace in an ssh session gave some output :-)

seemed to get a few lines further on my second attempt. maybe useful.

i dont know much about setting break points. you would have to hold my hand. am ssam on IRC

sorry, i pasted wrong. the last upload can be ignored/deleted.
the bonus new lines are:

write(0, "(II) Setting vga for screen 0.\n", 31) = 31
write(0, "(II) RADEON(0): MMIO registers a"..., 64) = 64
open("/sys/bus/pci/devices/0000:08:00.0/resource2", O_RDWR) = 9
mmap(NULL, 65536, PROT_READ|PROT_WRITE, MAP_SHARED, 9, 0

Thanks, I think that can help the upstream developers already. Can you please also attach the output from "lspci -vvnn"?

If you want to play with gdb, the above message is probably from RADEONMapMMIO() in src/radeon_driver. Maybe the call to xf86MapPciMem(). You can for instance set a breakpoint at the beginning of this function:
(gdb) breakpoint RADEONMapMMIO
(gdb) run
and then when it stops, use "next" to step through the lines.
(gdb) next

See also the gdb links on https://wiki.ubuntu.com/X/Backtracing

i think that needed to be "break RADEONMapMMIO"
ok. i nexted until it died. log attached.

I also tried booting with mem=512M and mem=1024M but this gave the same results.

also the slowness of GDB seemed to give it time to write the Xorg.0.log to disk. so i will attach that.

some further gdbing. thanks to tormod for the help

got even further this time.

I tried the 32bit alpha 4 cd. and it is broken in a different way. It seems to boot fine, but the screen is all white. compiz seems to be running, because if I do Super+E, i get the zoom out to see multiple desktops effect (zoom out to see 2 white squares).

That's sounds like a compiz bug. Does everything else work fine without compiz? Log in using a "failsafe gnome" session, or disable compiz with:
 touch $HOME/.config/compiz/disable-compiz

This fixed with the 20080829 live cd. either the new kernel, or the xorg updates must have sorted it. thanks

further investigation (booting with the 2.6.26-5-generic kernel), reveals that this was a kernel issue.
moving to 2.6.27 seems to have been the fix

I haven't been able to get this to work (Radeon 3650) with Alpha 5 64 bit live cd, or even if I install the full intrepid distro and then update it. Is the newer kernel part of the typical upgrade process, or should I wait for the next alpha (or beta)?

See https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/264462 for further details.

I have the same Card ATI Mobility Radeon HD 3650 and the same error. I tryed using Ubuntu 8.10 and 9.04 fully updated but nothing works. What was the fix?

I can also confirm this issue. I have Ubuntu / jaunty on lenovo t500. I tried to intall the latest (2009-07-23) driver from ati.amd.com (ati-driver-installer-9-7-x86.x86_64.run), but I got blank screen again.
