From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040809 Galeon/1.3.17 Description of problem: My monitor seems to be locked in some bad resolution/frequency and it seems i cant change it. The monitor resolution is way bigger than the 1600x1200 resolution i used to have. What i see on the screen is a normal-sized root window (with desktop inside) located in the left-top corner of the screen and some big black part in the bottom and right parts of the screen. I actually see something like that: http://livna.org/~anvil/the-xorg-x11-0.6.8-effect.png If i press ctrl alt +/-, the root window size changes but the monitor stay in the say resolution/frequency (and, btw, this is killing my eyes..). My video card is a old radeon 7200 : 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon R100 QD [Radeon 7200] (prog-if 00 [VGA]) Subsystem: ATI Technologies Inc Radeon 7000/Radeon Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping+ SERR- FastB2B- Status: Cap+ 66Mhz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 64 (2000ns min), Cache Line Size 08 Interrupt: pin A routed to IRQ 201 Region 0: Memory at f4000000 (32-bit, prefetchable) [size=64M] Region 1: I/O ports at d800 [size=256] Region 2: Memory at f1800000 (32-bit, non-prefetchable) [size=512K] Expansion ROM at f3fe0000 [disabled] [size=128K] Capabilities: [58] AGP version 2.0 Status: RQ=48 Iso- ArqSz=0 Cal=0 SBA+ ITACoh- GART64- HTrans- 64bit- FW- AGP3- Rate=x1,x2,x4 Command: RQ=16 ArqSz=0 Cal=0 SBA+ AGP+ GART64- 64bit- FW- Rate=x1 Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- The monitor is a mitsubishi 230SB and is well recognized by system-config-display. The configuration file didnt so much change from fedora core 2, but even Fedora Core 2 xorg.conf wont work. The monitor Horiz/Vert frequencies in the config file didnt changed since FC2. I'll attach X server output log and X configuration file. I strongly doubt this has something to do with my desktop configuration since it also happens with gdm/xdm and during the FC3T2 installation process. Should i say i didnt have this problem with X11 R6.7 in FC2 ? Version-Release number of selected component: xorg-x11(0:6.8.0-4).i386 How reproducible: Always
Created attachment 103973 [details] xorg.conf xorg.conf generated by "system-config-display --reconfig" in FC3T2.
Created attachment 103974 [details] Xorg.0.log The current X server output log.
Created attachment 103994 [details] errors after running moz-mail 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility U1 comparative.
I got the same problem with X11 6.8.1-3.
ping ?
Thanks for the bug report. This issue is being tracked as a FC3Target bug, and will be reviewed and assessed during the remaining Fedora Core development cycle. Once we have reviewed the issue, we will provide a status update. You may also wish to report this issue to the X.Org development team by filing a bug report in the X.Org bugzilla located at http://bugs.freedesktop.org in the "xorg" component. If you do file a bug report in the X.Org bugzilla, Red Hat will also track the X.Org bug if you provide the upstream bug report URL here, which may expediate finding a resolution to this problem. Thanks again for the report.
Mike : it's done. http://freedesktop.org/bugzilla/show_bug.cgi?id=1514
Thanks Anvil, I've added myself to the CC upstream.
I have seen this problem since first changes towards Xorg 6.8 X worked fine in FC3 T1. reported to Xorg bugz #1175
Just curious if anything has been heard from Xorg. I doubt many old radeon users will want to upgrade if they only have 1 video mode. (Unless of course they buy a new video card.)
Status update: This bug is a bug in the Radeon driver which no longer detects the Radeon BIOS correctly on this older hardware, causing it to fall back to failsafe defaults, only the failsafe defaults do not work on old Radeon properly, and assume connector[0] is a DVI panel, when on Radeon 7200, it is a CRT always. A quick ugly hack would be to add code to handle Radeon 7200 differently by making it fallback to CRT always, and then use the existing code for non 7200. As an additional side note, comment #3 is completely unrelated to this bug. For anyone experiencing this problem, please CC yourself to the upstream bug report where I've given a more detailed technical analysis of the issue, and will do followups in the future. Thanks.
A patch is available here: https://freedesktop.org/bugzilla/attachment.cgi?id=1130 that fixes this problem on my test system.
Ok, we've integrated Hui Yu's patches into our latest build, and it appears to work now on a variety of Radeon hardware. The SEGVs should no longer occur, however there are some problems with DDC detection occuring in the driver. The H/V ranges are read from the monitor ok, but the dimensions aren't. It acts as if EDID is ignored. I'm treating that as a separate non-critical bug however, as the desktop starts up in 1600x1200 seemingly ok for me now, although to get the correct DPI I have to specify the monitor dimensions as returned by "ddcprobe". Since ddcprobe can probe the settings ok, I assume the DDC problem is a driver bug. This particular bug seems to be fixed now. Please test the xorg-x11-6.8.1-12 build and let us know as soon as possible if it works for you now. TIA
Mike : it's pretty good for me. I have a 1600x1200 root window in a physical 1600x1200 resolution. Ctrl-A-+/- works. The randr stuff works too. I didnt notice anything bad in the current log (http://livna.org/~anvil/Xorg.0.log). xorg-x11-6.8.1-12 is Good For Me(tm). Thank you.
just got this update and my radeon 7200 works great now! Many screenmodes is very nice. Thanks to all! xorg-x11-6.8.1-12 is Good For Me Too
Thanks for the feedback guys! Glad this got fixed for FC3.
Hi! I don know exactly if my report is related or not. So, here it is: I have an old ATI AllInWonder128 (Rage 128 chipset). I usually have 1600x1200 and everything is OK. But when I try to logout or even shutdown from GUI, a bad frequency range is used and monitor complaints about it. All ctrl-shifts and so doesnt work. And even worse: the system itself freezes! I tryed to schedule a shutdown for, say, 2 minutes and meanwhile I logout. The monitor complaints as usual and shutdown never happens, even after hours. If i need to change user or shutdown, I have to ctrl-shift-F1 and force GUI restart (telinit 3 then telinit 5) or shutdown -h -y now. Thank you all Fernando Gomes fernando DOT gomes AT bigfoot DOT com
