[Bug 60639] New: RV635: Kernel displays black screen when monitor is connect via DisplayPort
https://bugzilla.kernel.org/show_bug.cgi?id=60639
Bug ID: 60639 Summary: RV635: Kernel displays black screen when monitor is connect via DisplayPort Product: Drivers Version: 2.5 Kernel Version: 3.10.3 (and earlier) Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: kernspam@schreib-doch-mal-wieder.de Regression: No
When the monitor is connected via DisplayPort I can see grub but once the kernel takes over, the screen goes black. When the same monitor is connected via DVI everything works.
Adding the kernel option "video=DP-1:1920x1200@75" makes at least the kernel messages and virtual consoles work. However, when X starts the screen goes black again. This might be related to the bug reported here: https://bugzilla.novell.com/show_bug.cgi?id=752593
Modeline from EDID: Detailed mode: Clock 154.000 MHz, 518 mm x 324 mm 1920 1968 2000 2080 hborder 0 1200 1203 1209 1235 vborder 0 +hsync -vsync Monitor ranges (GTF): 50-61Hz V, 30-83kHz H, max dotclock 170MHz
Kernel 3.10.3 (but also tested with 3.9.x and 3.8.x)
Graphic chip: ATI Mobility FireGL V5700 (the second intel chip should be disabled)

--- Comment #5 from douglas_peale@yahoo.com --- I can confirm that the patch did not fix the problem. I folowed these instructions to build the kernel: https://wiki.ubuntu.com/KernelTeam/GitKernelBuild . I went to manually edit the atom.c file, but found that the changes had already been applied in the version I downloaded. I will now attempt to add the requested files

--- Comment #9 from douglas_peale@yahoo.com --- I will note that the system is currently set up with two monitors, one dual-link DVI (the one I am using to enter this message) the other Display port that was working up to grub, then it shut itself off after the grub screen. The stuff in xrandr.output about nothing being connected to the display port is incorrect.

--- Comment #10 from Alex Deucher alexdeucher@gmail.com --- Can you please attach a copy of your vbios?
(as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom

--- Comment #12 from douglas_peale@yahoo.com --- Has there been any progress on this? I am very near throwing money at the problem and buying an NVidea card. At least then I can plug in whichever brand currently has working drivers.

--- Comment #14 from douglas_peale@yahoo.com --- I am afraid I threw money at the problem and solved it by buying an Nvidia GeForce GTX760. After a year and a month since I originally reported this bug on Launchpad.net, apparent lack of activity on this site, video breaking for mythTV every other update to ubuntu, I'd had enough. I am currently running the setup I originally intended: Dell 2560x1600/60 monitor on dual link DVI next to my BenQ 1920x1080/120, on display port both in landscape mode. MythTV is playing video without dropping frames or stuttering audio. I got this setup working not more than an hour ago, after the most frustrating, difficult driver instalation I have ever experienced. But this is a configuration I was never able to achieve with either the propriatary drivers from ATI (when they were still available), or the open source drivers. I hope you eventually succeed in making these drivers work, but I could not take it any more.
