different card, same problem here. My graphics card is a HIS Excalibur Radeon 9600PRO Dual DVI, both heads are DVI connected. The secondary head is shutting off for about a second from time to time. The problem seems to be related to redraw operations on the primary head (e.g. scrolling large screen areas). Config: Distri: Debian/sid XOrg: Ubuntu Packages 6.8.2-2 Linux kernel: 2.6.10-1-686-smp (debin/sid version) Mobo: ASUS P4P800-VM Memory: 1Gb some more details - the flickering only occurs when the second monitor is connected via a DVI connector - a Dell LCD FP does not go dark, but instead flickers - a ViewSonic LCD switches of for about a second - if the second head is connected via a VGA connector no problems occure Summary: there is some kind of signal curruption on the seconday DVI only Pitily, there is no progress here, as I understand. I'm not sure at all that such switches are healthy for a monitor. Seems that I need to build 6.8.1 and switch back to it as there was no such a bug there. Same thing here. Dual head w/Radeon card driving one head. Under xorg 6.8.2 I get the DVI Radeon-attached monitor blinking off then on again regularly and with inconsistent frequency, but it can happen as quickly as every few seconds. It's apparently associated with screen updates, since the blinks can be tied to new window popups, mouse moves, etc.. The secondary head is a DVI monitor connected to an i915 onboard video, and it never hiccups. Downgrading to xorg 6.8.1 has made the problem go away. I've seen the issue with assorted Fedora Core 3 stock SMP kernels (2.6.10 and 11). My environment is Gnome based. My xorg.conf is available at: http://www.eol.ucar.edu/~burghart/xorg.conf Also, this bug seems to be described for a single-headed system in the thread at redhat.com beginning here: https://www.redhat.com/archives/fedora-list/2005-April/msg00046.html Note that in that thread, changing to a VGA connection to the monitor also makes the problem go away. I have the same problem with xorg 7.0 (Fedora Core 5), so I don't see this bug resolved. Hardware: IBM T42p thinkpad, ATI FireGL Mobility T2, xternal TFT monitor (1600x1200) connected via docking station What is the status if you are using the current version of xorg (7.1)? Hi. I switched to Xorg 7.1.0 (Mandriva's cooker distribution) and I can't use the fglrx driver anymore (module incompatibility). Using the radeon driver with my FireGL Mobility V5000 results in my screen flickering like crazy, very much like the pictures at: http://www.sisis.de/~guru/xorg/flicker.html I am able to somewhat stabilize the image horizontally using xvidtune but I can't get rid of the "echo" and horizontal lines that keep moving up or down my screen. I tried all the options people advised, without success. I had the same problem with Xorg 6.9 (or earlier) when I bought my computer in November. At that time, I switched to fglrx and it fixed my problem. Another report on the same problem at http://avkrok.net/nw8240/ If my problem is not really related to the bug described here (sorry), I'll file a new bug. Let me know if I can provide data that would help fix that issue. (I am not sending my configuration file since I have the same problem with all configurations I tried.) Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status. Sorry for this janitorial spam, you know where to send hate mails to when your inbox gets full of bugs you're subscribed to. |
