Black Screen on digital connector mode set.

[SeanCollins]

seen on 5770 and 5870, logs attached, Black screen after boot splash. I get the typical scrambled screen at startup, then the monitor just turns off.

[SeanCollins]

observed on gcc4h and gcc2h builds as discussed on irc

[mks]

I can confirm this behavior on a 5450. Can provide syslog, if needed.

[Bouncer]

Have observed the same on 6770. Can provide a movie (about 4.3 Mb) if so desired.

[Disreali]

Thanks, but we don't really need a movie. A syslog would be more helpful. See here for info on finding it

try post hrev43810. hrev43810 fixes a *big* oops.

[mks]

Doesn't work for me. The screen still turns of shortly after the "rocket" icon. The system seems to respond though (doesn't lock up): I can shutdown by pressing the power button or hold Ctrl-Alt-Del for some seconds to reboot.

Attaching syslog …

syslog with hrev43810

[SeanCollins]

I tested43810, no sucess.

this worked back in early january and mid to late december iirc.

New log, from 48380 gcc2 hybrid, further note, this is a dvi to hdmi cable on a hdmi monitor. 1920x1080 23 inch. If that matters at all.Tried using both dvi ports. Result is identical.

Just tested 43877. The shortly visible scrambled screen is gone, but the display still turns off after the rocket.

kallisti5, I wonder how I can support your awesome work on the driver. Is the problem, that you have no 5xxx card? If so, would it help at all, if you had one? There are used 5450s on Amazon for USD 25. Let me know and I'll get you one delivered.

[kallisti5]

hrev43900 solves a big issue with mode setting, please give it (or a later version) a try!

[mks]

Sorry, still no luck with hrev43901 on my 5450. Screen still switches to stand-by after boot splash. In case it matters: the syslog says the card has HDMI, 2x DVI and VGA, but it really has only 1 DVI, not 2.

[kallisti5]

Moving to Blocker for release. This is the symptom of a more general mode setting issue with digital outputs on Radeon HD devices.

[SeanCollins]

These cards work fiarly well with vesa. Are you sure you want to block alpha 4 over this ? I mean I'd really appreciate the increased priority on a personal level but its not like Haiku r1a4 can't get by without a radeon Hd driver.Users have been doing it for sometime.

Is there anything I can do or help with testing wise ? I can now build but understanding the git bisect functions is a bit confusing to me to say the least. If you can help me, I'll test the revisions down to when it last worked to help you get this fixed.

[SeanCollins]

Ok, before my eyes bleed here.

The last working rev I tested was 43489

The first radeon_hd rev that I tested that does not work is 43503

Do you need me to go further or is this close enough ? I am also attaching the last hd5xxx driver that I can find that works to the ticket, for anyone lurking the ticket.

hrev43489 works hrev43490 works hreb43493works hrev43497works hrev43498 works hrev43501 works

hrev43503 broken tested twice

Rev 43503 broke the driver.

[kallisti5]

fixed in hrev44056 :D

[mks]

I just want to confirm that this works, in case nobody did yet.

[SeanCollins]

Fixed
