backlight control lost after resume - screen black after hibernate
Hello, I run Wheezy on a quite new sony vaio PCG laptop with GeForce GT 555M (GF106) and a second intel 2D video card and nouveau FB. After resume from suspend or hibernate, the backlight control gets lost. I still can echo and cat to /sys/class/backlight/acpi_video[0,1]/ but it has no effect. After a fresh boot, everything behaves as expected and e.g. FN-Brightness keys work well. This is especially annoying since at hibernate-resume the backlight is switched _off_ and there is no way to switch it back on anymore. It is actually off which can be seen when the memory is restored from disk and the cursor is blinking in the corner, one can see a slight shine at the edges of the display which disapperas immediately after. The system however is resumed and working, it can be shutdown -r now 'blind' or be accessed by ssh. There are a lot of descriptions about the backlight not being restored to the correct value but there is nothing about the /sys/../backlight branch being without function after resume at all.

It can be a bug in the nouveau driver, like this: New: Backlight off after suspend-to-disk on Powerbook https://bugs.freedesktop.org/show_bug.cgi?id=31120 or this one: Brightness stuck to low value after suspend/resume https://bugs.freedesktop.org/show_bug.cgi?id=39550 You can: - Try blacklisting nouveau for hibernating - Try with another driver (the nvidia closed one) Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

console screen black out
Hi all... How do you change the amount of time when your at the command prompt and the screen goes blank? I know xset is used in Xwindows... but how do you set it for just regular logins... Will this setting be saved after a reboot? Thanks Mike

Take a look at man setterm setterm -blank 5 ^ time Putting the command in .bashrc and source it to .profile.

You don't give much in the way of details, but if you use X, then try xset s noblank or xset s 601 not tested, but the first should completely disable screen blanking, while the next one should delay it by one second ;-) (of course, you can change 601 seconds to whatever you prefer). -- Brian May [EMAIL PROTECTED]

In X, or at a virtual terminal? In X, at any xterm or rxvt or whatever prompt, type xset x noblank at a VT, at a shell prompt type setterm -blank 0 Of course, you could put these into scripts to automate the process. -- Carl Fink [EMAIL PROTECTED] I-Con's Science and Technology Guest of Honor in 2000 will be Geoffrey A.

Thanks, Ron Try using this command: setterm -blank 0 Then put it in ~/.xinitrc or ~/.xsession.

Try putting 'setterm -blank 0' in your .bash_profile file. (Bah, I think I might write a decent man page for setterm. I could certainly do better than the existing one.) -- Colin Watson [EMAIL PROTECTED]

It is in the util-linux package which is a required package so should be on your system already. It lives in /usr/bin.
