Bug 78693 – No dvi w/ ati-drivers-8.8.25 and xorg-x11-6.8.0-r3

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Garrison 2005-01-19 10:15:31 UTC]

After upgrading to ati-drivers-8.8.25 and xorg-x11-6.8.0-r3 I no longer get a signal on my dvi port.  I'm running a dual-head setup, but the results are the similar if I switch to single head (i.e. no dvi).  The vga port works fine, and as far as X is concerned the dvi display is running, but the monitor displays NO SIGNAL.  Both monitors/ports work fine at the console.

Reproducible: Always
Steps to Reproduce:
1. emerge -vp ati-drivers xorg-x11
2. reload fglrx
3. startx

Actual Results:  
No errors, but no dvi output either.

Expected Results:  
There should be blinkenlights on my monitor.

I had to recompile ati-drivers with CFLAGS="-01" to get things like glxgears to
stop segfaulting, but this hasn't solved my display problem.

Same probleme here :)

[Comment 6 René Marten 2005-01-29 01:44:21 UTC]

same here, my L1925 switches to power saving mode and the only thing to get it work is to plug the analog cable and switch to analog output. But it's no solution at all.

[Comment 7 Luca Barbato 2005-01-31 18:09:24 UTC]

Could you check if -O2 is enough to ensure a correct kernel module?

I'll force -O1 on the stable ebuild as cautelative measure if isn't

I am having the same problem on my amd64 system, also on a Radeon 9200 (rv280).  Analog output works, but DVI does not.  There are no errors reported, and the log even shows that the monitor (an LCD screen) is being detected correctly via DDC, including the correct native resolution, etc.  But all I get is a blank screen, as if the monitor were in power-save mode.  If I use x.org's open-source radeon driver, DVI works just fine.

I don't think my logs would show anything not shown in the attachments from the original reporter, so I won't bother adding mine.  If anybody wants more details on my system, please ask.

Same problem, but with ati-drivers-8.10.19 and xorg-x11-6.8.2-r1 on 2.6.11-gentoo-r3 kernel. No matter how I do configure X, only analog display is active. Switching monitor (LCD EIZO) to DVI makes it 'suspend' like there was no signal. Couldn't find any solution for this, tried to recompile ati-drivers with different flags.

This really hurts, as I have to downgrade xorg now. *sigh*

It's the same here even with the newest ati-drivers-8.12. I have spotted the problem in every X.Org version from 6.8 above. Last combination that worked fine for me was X.Org 6.7 and the last ati-driver-3.

[Comment 11 Matthew Tippett 2005-08-17 21:33:25 UTC]

Please verify with 8.16 series driver.

[Comment 12 Jan Zeman 2005-08-25 01:01:50 UTC]

Yes, 8.16.20 driver solved for me this problem at last. After emerging I just
used fglrxconfig - no need to play with setup of various options like
MonitorLayout, which had constantly been of no use. Tv-out works without
problems as well.

Garrison (and everyone else), could you confirm this solves your problem?

[Comment 14 Garrison 2005-08-26 08:36:49 UTC]

Sorry Joshua, I opted to switch to a GeForce card so I am no longer using
ati-drivers

[Comment 15 Joshua Baergen (RETIRED) 2005-08-26 09:23:54 UTC]

Thanks for letting me know :)

I'll mark this as fixed unless someone else tells me otherwise.
