No problem, I'm just glad someone's trying to help :) One little comment though: avivotool is not included in the binary radeontool package, I had to compile it from source. Since I'm not sure which two cases you're interested in (I think the KVM switch is no longer the issue), I'm again attaching all three cases: *_1screen: no external monitor, everything works *_2screen: external monitor (directly connected): black screen *_kvm: external monitor (connected via KVM switch): black screen ** Attachment added: avivotool_1screen.txt http://launchpadlibrarian.net/21850302/avivotool_1screen.txt -- [radeon] xorg gives black screen with external monitor connected through KVM-switch https://bugs.launchpad.net/bugs/257941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 257941] Re: [radeon] xorg gives black screen with external monitor connected through KVM-switch
Hi Rico, I have to apologize, I asked you for the wrong info. Upstream tells me that radeontool output is only valid for pre-R5xx series chips. For r500 and newer, including the R500-based X1400, they actually need the output from avivotool. This probably explains why you saw no difference between the two radeontool outputs... avivotool is in the radeontool package, so you already have it installed. Would you mind please re-running your two cases again, and instead collect the output from avivotool? Run it like this: avivotool regs all avivotool_good.txt Thanks ahead of time, and sorry for the incorrect directions I gave. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Triaged = Incomplete -- [radeon] xorg gives black screen with external monitor connected through KVM-switch https://bugs.launchpad.net/bugs/257941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

OK, the following results are with a fresh install of Jaunty Alpha 3. The external monitor is different, but the bug is the same. I'm attaching three different sets of Xorg.log and the radeontool output: *_1screen: no external monitor, everything works *_2screen: external monitor (directly connected): black screen *_kvm: external monitor (connected via KVM switch): black screen there seems to be no (major) difference between the Xorg.log/radeontool output from the kvm setting and the one where the monitor is plugged in directly. ** Attachment added: Xorg.0.log_1screen http://launchpadlibrarian.net/21286286/Xorg.0.log_1screen -- [radeon] xorg gives black screen with external monitor connected through KVM-switch https://bugs.launchpad.net/bugs/257941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also, the output from xrandr and get-edid is identical, no matter how the monitor is connected. Well, that's a good sign - implies that the detection is working the same regardless of whether the kvm is present or not. But we'll have to see once the current bug is resolved.

Meanwhile, as to what could be causing the black screen failure, with these kinds of issues the next step is usually to collect register dumps from both a) when it is working, and b) while it is failed with a black screen. In Jaunty we've updated the radeontool utility for this purpose.

Thanks for your response. With a freshly installed Intrepid (and all upgrades) there has indeed been some development. X11 still fails, but independently from whether the KVM switch is attached or not. Also, the output from xrandr and get-edid is identical, no matter how the monitor is connected. I'm attaching both Xorg logs (xorg.conf and xorg.conf.failsafe have been deleted; monitor is directly attached) and the output of both xrandr and get-edid (monitor directly attached). ** Attachment added: edid http://launchpadlibrarian.net/20035699/edid -- [radeon] xorg gives black screen with external monitor connected through KVM-switch https://bugs.launchpad.net/bugs/257941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 257941] Re: [radeon] xorg gives black screen with external monitor connected through KVM-switch
Hi Rick, Sorry it's taken so long to respond to this issue. Are you still experiencing it with the released Intrepid? It sounds to me like the KVM is somehow corrupting the EDID data provided by the monitor. There are two useful tools for looking at the EDID information: xrandr --verbose and, from the read-edid package: get-edid | parse-edid I would suggest running each of these commands once with the monitor directly attached, and once with it through the KVM. See if there are any notable changes, and attach all the output from these commands. Meanwhile as a workaround, you could also experiment with the IgnoreEDID or NoDDC options (see `man radeon`). ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Confirmed = Incomplete -- [radeon] xorg gives black screen with external monitor connected through KVM-switch https://bugs.launchpad.net/bugs/257941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

just a small fix to the description. All log files so far are from failed attempts with the ext. monitor connected.
