[Ubuntu-x-swat] [Bug 1168188] Re: black screen on lenovo g580 and ubuntu 13.04
FYI, I noticed that if I use the Fn+F4 key on my laptop (which is the
'lower screen brightness' function key) and drop it to 0% (as reported
by a screen brightness overlay in KDE, if I'm logged in), my backlight
goes completely off, to the point that I cannot see anything on the
screen (similar to the problem I have when I boot up without an external
monitor plugged in). Pressing Fn+F5 ('raise screen brightness'), it
comes back on, of course.
So the echo ###
/sys/class/backlight/acpi_video0/brightness-in-/etc/rc.local trick
sounds like it will work. I'll test it later today, and report back.

I tried, and as with Ron A. in comment #5 to this bug, I, too can 'blindly' log in to my KDE desktop after entering my password. (So basically, the screen goes completely off, then KDM comes up). After logging in, the screen becomes active again. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1168188 Title: black screen on lenovo g580 and ubuntu 13.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1168188/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1168188] Re: black screen on lenovo g580 and ubuntu 13.04
I just upgraded from Kubuntu 12.10 to 13.04, and have been struck by this. Unless I attach my external monitor (via HDMI) during boot, my laptop's LCD goes blank after showing the Kubuntu logo for a few seconds. I know it's getting to the KDM login screen, since if I move my mouse down+right, then click, the system powers down. (The shutdown button is at the extreme bottom right.) Attached is the output of 'intel_reg_dumper' on my system, after successfully logging in (booting with monitor attached). ** Attachment added: Output of intel_reg_dumper on a ZaReason Strata 5330 laptop with Intel video (lspci says: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)) https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1168188/+attachment/3658488/+files/intel_reg_dumper.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1168188 Title: black screen on lenovo g580 and ubuntu 13.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1168188/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
