I am wondering if it is possible turn off my display with a key of my laptop's keyboard. I mean if I press ctrl + o then my display turn off and then if I press ctrl + o my display turn on.
I decided to update all the software on my computer. Fortunately, it upgraded kernel version 3.14 to 3.16. I was happy to learn that suspend now worked on my laptop by calling pm-suspend, but it did not worked by closing the lid. So I search and found on debian's website that installing systemd and adding some config lines in /etc/systemd/logind.conf would sove the issue. So I followed the procedure and did like instructed, to end up with a computer that boots on black screen.
The last verbrose line I see on boot up is "kvm disabled by bios" and then it shutdown down the screen. The computer works, as I can login and shutdown by doing those operation blindly.
I tried removing systemd but it still does not work. If I use the old kernel 3.14 I can boot without any problem, but if I use kernel 3.16, I boot to a black screen. I remember successfully booting in 3.16 before installing systemd.
My system goes through slow periods where it just crawls and others where it's fine, but I'm wondering which service settings are OK to just shut off to give me a bit more oomph when I boot up.The others I'm pretty OK with like spam assassin, dictionary server and so on, but some of the others i wonder if they only serve to slow things down..Also..I live in a very dusty environment and I KNOW the fans and other parts get caked with dust and it wouldn't surprise me if the dust got so bad it just stops the fans completely so once in a while I use my air compressor to blow the crud out and I usually get covered myself, but how safe is using the compressor? It's not the type that typically fills up with condensed water droplets so that isn't a super critical issue..It's a small 1 hp deal, elect drive and so on.. Safe enough? It's all I have and/or can afford..

Background: I am running Debian 8 with the Xfce DE on my Toshiba Satellite Laptop.
When at home I will connect my laptop to an external display. I did the same while I was running Ubuntu; however, with Ubuntu I could activate my laptop display by simply disconnecting the external monitor. With Debian + Xfce, unplugging the external monitor leaves my laptop screen blank.
In order to activate my laptop display, I have to open Display settings, turn on laptop display -- which still leaves my laptop screen blank -- and then switch resolution: there are two listings for 1366x768 under resolution, and only the second one restores my laptop display. Please note that if I have both displays on at the same time the size of the output on my external monitor will be reduced to about the size of my laptop's display.
I would like the create a Bash script which can automatically switch between my displays. After some Googling it seems like xrandr is the tool I need for the job. However, I have been having trouble getting it to work.
I tried the command Code: Select allxrandr --output LVDS1 --auto --primary --output HDMI1 --off. This however just turns my external display off without turning on my laptop's display. I suspect this has something to do with the fact that LVDS1 has two modes at 1366x768; perhaps only one of them can actually display? I'm not sure, but anyways here's the output of xrandr:
Code: Select allScreen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
1366x768 59.99*+
1360x768 59.80 59.96
1024x768 60.00
800x600 60.32 56.25
[Code] ....
Is there a way I can specify that xrandr should use the second 1366x768 mode?
I just realized that the second mode is, in fact, 1360x768 rather than 1366x768...

Today I installed debian-8.1.0-amd64 on my older Samsung Laptop (Model r560). The installation without a desktop environment worked fine and the system booted without any problems into the virtual console. There was however one problem: when I was away from keyboard for some time, the screen turned black and when I came back and hit a button to wake the system up, the laptop immediately restarted. Later I installed the gnome desktop environment. This also worked fine.
But whenever I try to change the screen brightness in the gnome-shell, my system immediately restarts and successive attempts to boot debian fail. Some time later and after countless attempts to boot debian, it finally does boot again. By "debian fails to boot" i mean the following: The initial ram disk is loaded and fschk runs. Usually the system suddenly reboots at this point. SOmetimes, however, the video mode changes, the console font is changed and some services are getting started, but then at some point the system also restarts. I don't reach the point where a login prompt appears, or the graphical environment starts up.
Assuming, it has something to do with buggy acpi implementation of my hardware, I tried the following:
I tried to disable acpi completely by using the kernel parameter "acpi=off". This doesn't work and causes the kernel to hang
I tried to start debian without using a GUI using the single parameter. This also didn't work.
acpi_backlight=vendor also did not fix the problem.
I'm using a laptop as a mini server, but I haven't figured out how to sleep the display. I am not using the gnome desktop - I shut the lid but the display stays on.
ps - I should note - this is Debian 5.0.3 PPC version running on a PowerBook G4
Until a while ago, I had to problems sshing into my laptop, whose static IP is 192.168.1.64. I scp'ed a few files from it to my desktop, whose static IP is 192.168.1.22. Then, suddenly, I started getting a "destination host unreachable" error. I also get the same error when I try to ping the laptop. I verified that the ssh daemon was running on the laptop, and even rebooted, but I am still getting the error.
I didn't install any upgrades or edit any configuration files on the laptop between the time that ssh was working and when it stopped working.
Otherwise, networking works on the laptop. In fact, I am writing this post from it. It is as if my laptop suddenly decided to block incoming traffic.

I have installed Squeeze on my laptop, an Acer 5315.The fans never turn on, and the laptop eventually overheats and shuts off.This is not a hardware problem, because Lenny, on another partition, works fine.I have poked around, and discovered that the temperature sensor, as reported by "acpi -V", and in /sys/devices/virtual/thermal, does not get updated. It seems to get read at boot, but the reading never changes, no matter how hot the machine gets.
Specifically, if the machine is cool, acpi reports 40 degrees C, and goes on reporting the same number until the machine overheats and shuts down.On the other hand, if the machine is hot (because it's been running without the fan), and I reboot, then the reading at boot is usually either 75 or 85, and the fan turns on during boot, and stays on, at high speed, until the next reboot, and the reading never changes during the whole time
How do I change amount of display Hertz in VC? I have a conjecture that it's not the same as in GUI (on my computer). Ubuntu 10.04, Gnome. if not Debian, but at least it's close.

I have and ssd drive in old laptop that i want to move to the new laptop. To my knowledge i think i can replace the 1TB hard drive on new laptop with ssd, remove or reinstall or update drivers so the ssd will just run fine on new laptop without having to reinstall all the stuff and customization. Should i recompile the kernel in linux for new hardware? AFA windows 7(Dual booting Debian 8 and Windows 7), i think removing and reinstalling drivers will work fine.

My IBM Thinkpad T42 laptop fan is constantly running when the laptop is open.I only use AC power.Fan turns off when laptop is closed, which I did by selecting Suspend in Power Management.
cpufreqd and cpufrequtils are installed. cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor' is 'ondemand'
Constant fan was not a problem in XP Pro; I just installed Debian one month ago.
I have installed squeeze on a HP notebook. I have one small problem though.It does not resume from suspend. If I shutdown -> suspend, or close the the lid, or shut downs (suspends) as expected, but whenower it backup up, the screen just stays black.Hibernate is working fine.

Just resently I managed to activate internal bluetooth adapter. I'm not expert in command line and everything I could was done in GNOME. Same like most other systems an icon appears in panel bar whenever I used to type <modprobe omnibook ectype=14>. It took me some time to set everything with the kind help from URL... So the thing is that after fingering with some newly installed packages concerning b-tooth utilities that icon is gone and b-tooth is not active.

My laptop gets very hot within 10 minutes whether I do any task or not. Also battery life is almost 40% as compared to Windows. I am more worried about temperature as it remains completely cool in windows. Mostly CPU load remains around 10% and CPU spends 99.99% time at 800MHz clock.

On my Laptop, I installed Debian under the file "/" and the partition on which I have all my files under "/var". While this isn't really a big issue, when I originally installed Debian, I had the intention of having all of my files on a partition that I would auto-mount later so that when I upgrade my system by reinstalling it, I would only have to change the system partition and let everything else stay the same.. I can live without changing my /var if I can only do so by a re-install...

Despite having the Gnome Power Manager set to put the display to seep after 30 minutes, it always happens after 5 minutes. The display will go blank but still lit, and then it powers off after the 30 minutes. Surely, if I set it to 30 minutes, the display should power off then, and not just blank after 5? I have no screensaver packages installed so it's nothing to do with that.
