rv370 X300 Radeon Xorg.0.log on Fedora 23 (2 connected displays)(hwinfo
prepended)

I managed to reproduce the screen corruption accidentally, by forgetting to
disconnect 1680x1050 LCD on VGA before booting with 1920x1200 LCD on DVI.
Rebooting with only 1920x1200 on DVI, no corruption was evident in KDE.

The corruption looks the same as appeared long ago on a couple of rv370-380 era
Radeon X### cards I then decided must have developed bad RAM.

The problem is that the max texture and render target coordinate limits on R3xx
hardware is 2048 pixels.  If your desktop is larger than 2048 pixels in either
dimension, you will see corruption if you compositor attempts to accelerate it.
 The desktop compositor should check the GL limits of the underlying driver
before blindly specifying surfaces larger than them.

Hi Alex, you've responded to Felix comment but this is not the original
problem. 

As far as I know, my desktop size is 1920x1200 and doesn't exceed 2048 in
either dimension.  My card only has a 2 physical outputs DVI and S-video.  Only
DVI-0 is connected, so there is no "other monitor" left open that would change
the desktop size.

(II) RADEON(0): Output VGA-0 disconnected
(II) RADEON(0): Output DVI-0 connected
(II) RADEON(0): Output S-video disconnected

Nevertheless...

The only hint that I have so far is the "r300: CS space validation failed."
message. If it's a problem with the desktop compositor violating the contract,
which Gnome component is reponsible? Just trying to log the bug at the right
level.

I'll try using another desktop environment tonight.

Thanks

Not just another DE, but another OS, like a Knoppix DVD or other live media, to
help determine whether a software problem, or failing X300 RAM. If it's RAM,
maybe trying a lower resolution mode or display would tell that your real limit
has dropped to less than 2048. Was your X300 manufactured by MSI, or shipped
originally in a Dell PC?

It's probably assigned correctly now. The message indicates that the r300
driver isn't coping with the amount of VRAM available to it.

My X300 came in a Dell PC.

Didn't have the time to try another distribution but I remember having similar
display problems while trying Ubuntu from a Live image. Same problem under KDE.

At 1280x1024, I get the "CS space validation" error message.
At 1280x960, I don't get it.

I think what's happening is RAM deterioration. IIRC, my oldest and most used
(24/7 > 5 years) X600 started displaying the same kind of corruption. I
replaced it with another X600 off eBay for $6. Another I bought off eBay worked
OK at boot and on vttys, but corrupted like yours on starting X at modes higher
than 1280x1024 or so. With yours having only DVI and S-Video outputs it sounds
like yours came in a SFF Dell. I see a 5-lot of low profile X600 cards in a
current eBay ad for $19.95 delivered in the USA, and many other ads for X300
and X600 at low prices in US and abroad.

That couldn't explain the error messages Jean-Philippe is getting. They
indicate a software bug.

You wrote "the r300 driver isn't coping with the amount of VRAM available to
it". I would expect unreliable RAM to be difficult to cope with. Bad coping may
be a software problem, but if his coped with available RAM is less than it used
to be, I'd expect he wouldn't be able to recover uncorrupted 1920x1200 without
hardware replacement.

I think I may still have my corrupting rv380 X600 upstairs that I could
reinstall in something if you think it might help development of better coping.

Felix, the symptoms described in this bug report aren't consistent with
hardware failure. Some of the symptoms you were getting due to hardware failure
might have been similar, but it's most certainly not the same problem. Please
stop mixing up the two issues.
