Description of problem: hi I am having black screen when I hit Fn-Home (Brightness up) on my Thinkpad X60. The birghtness up hotkey works fine in console and I am able to Ctrl-Alt-F7 back to Xorg. But It will not work under Xorg and Xorg is still running. Changing run level from 3 to 5 back and forward will get the screen back. The intel driver kinda fix the black screen problem. When I hit Fn-Home, it goes black screen, by release the key Home then Fn. I am able get the screen back. But it hangs up or black screen when I try to restart or shutdown from GDM. The vesa driver works still but without Xv. I try the following without luck. * enable the acpi video.conf * update driver to 1.7.2 on but i810 and modesetting Version-Release number of selected component (if applicable): xorg-x11-drv-i810 How reproducible: hit Fn-Home Steps to Reproduce: 1. On GDM or login to Xorg after boot 2. Hit Fn-Home Actual results: Black screen Expected results: Additional info: The vesa driver works still but without Xv.
It also happen to RHEL 5 Beta 2
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thanks in advance.

It looks like the brightness up key has been remapped to the "Switch display" key (toggle between CRT/LCD/both). We have noticed this on T60 laptops, which run a very similar card: 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)

I see the same problem on F7 test 3.

Isn't this DUP of bug 236500?
Doesn't look quite like a dup to me. On a Thinkpad, the symptoms are different to the Dell symptoms reported in bug 236500, even though the graphics hardware seems similar in both cases.
This problem (on my X60) went away for me with updates and/or a change to the 'intel' Xorg driver. I'm running Fedora rawhide, and was seeing this before.
Really, driver intel does not blank when I click Fn+Bright keys. But the switching is not smoothly (~2sec black screen, than ~1.5-2 sec brigth rises to need value). The gnome-power-manager works fine (without any delay on switching). I consider it inconvenient for me.
BTW, I still have this problem. I have to ensure that video.ko isn't loaded.
Yes, the driver "intel" doesn't exhibit this problem, but the driver "intel" also doesn't seem to support dual-head mode so it's a non-starter. I see this problem on an up-to-date Fedora 7 system running on a Thinkpad T60.
Fedora Core 6 is no longer supported, could you please reproduce this with the updated version of the currently supported distribution (Fedora 7, 8, or Rawhide)? If this issue turns out to still be reproducible, please let us know in this bug report. If after a month's time we have not heard back from you, we will have to close this bug as CANTFIX. Setting status to NEEDINFO, and awaiting information from the reporter. [This is mass-filed message to all open Fedora Core 6 bugs related to Xorg or Gecko. If you see any other reason, why this bug shouldn't be closed, please, comment on it here.]
Reporter, could you please reply to the previous question? If you won't reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
I can confirm that this problem still exists on Fedora 7.
I have switched to the intel driver from i810. It works in the F-7.
Yes, but as I said in comment #16, the intel driver cannot operate dual-head.
(In reply to comment #21) > Yes, but as I said in comment #16, the intel driver cannot operate dual-head. I did not test it, but the manpages indicate, that this should work. Look for randr in man xorg.conf and man intel
xrandr allows you to have a single virtual screen that crosses over onto two displays, but it doesn't let you have two screens. Using xrandr, the gnome panel moves over to the VGA screen, and the two "displays" share :0.0 instead of putting the LCD on :0.0 and the VGA on :0.1. Apparently this is called "zaphod mode", and the intel driver seems not to support it. Thanks, but no thanks.
Well, it's unlikely that i810 will get any better at handling the brightness keys... And yeah, unfortunately zaphod mode isn't supported in the intel driver, but there is an upstream bug for it, so we might fix it for 2.3.
I posted my bug on this issue under https://bugzilla.redhat.com/show_bug.cgi?id=239332 An "upstream bug" has been alluded two on several threads related to this, but nobody is posting the location to this bug so I can put a tickler on it. This error is one of three primary failures which forced me back to Windows from my beloved OS.
Derek, I think intel can handle dual-head pretty well, only you don't use Xinerama and stuff but you have to play with xrandr command. Are you able to switch to "intel" driver, please?
The Intel driver has been a source of random crashes and freezes for me, so it's hard to consider it as usable.
Matej, Sorry I didn't respond earlier to comment #26, but see Comment #24. The Intel driver doesn't support zaphod mode, which is exactly the feature I'm looking for, and why I have to use the i810 driver. There's no way to use xrandr with the intel driver to get a :0.0 and :0.1 screen, both with gnome panel, and having them with separate sets of windows/geometries/etc.
yeah
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Just curious -- does anybody see this bug still in the alive?
I still see it, but I'm still on Fedora 7. I've been on the road too much to have time to update my laptop. MAYBE I'll update to F9 in a couple weeks, but I suspect I wont get to it until the end of October. So if you don't mind could we keep this bug open until then?
No problem.
just to keep this alive
ping? any development?
