Monitor To Sleep After 10 Minutes

Before i start id like to say im a total newb to linux.. Used windows for years but I'm not tech minded, my old pc run slow so i bought an ipad! Then was given a linux pc but a good friend about 4-5 years after buying an ipad.


Brief history
A friend of mine the other day gave me a pc he had lying around unused but dusty and had linux installed. i got it home and it worked perfect but no sound, messages him and i was told by a him to locate the "analog output" click that in settings and make sound run through it, all i could find was dummy output ( i think its called ), i researched it and found its because it was bugged so to sort it out i needed to uninstall and reinstall so i followed some guys code and did that.. It said the install was successful in the control panel type thing. but on restart i get a blank screen.. Like my monitor isn't working! " i used this method http://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ no sure if links are allowed but i used this guys method to try and get my sound back and ended up with a blank screen after restart.

I get to the grub menu ( think its called )

I have found many post relating to blank screen but non are like the picture i posted or talk really in death tech talk which i don't understand.. I think in the grub menu i need to change something but I'm confused

I believe its when you reinstall stuff that it makes the monitor not work?? Could this be the case?? If so can you help??

Ps sorry if i posted in wrong section i am a total newb so please forgive me

And no in death tech talk, try keep it simple

Thanks commando.

Ps if you want me to explain things further please say. I'm not computer literate sorry but i will do my best.

Hi this is my first post. I'm a Linux user but far from an expert. I'm building a CNC machine and it will be powered by linuxcnc, I may try to compile it for my more modern hardware.

My question is because I have some old cases with touch screen monitors that were likely from some sort of kiosk. The built in monitors have odd Samsung lcd panels with a native resolution of 1024x768 but they are wide screen. They look like 16:9 but could be 16x10. Certainly not 4:3. Thus the pixels are rectangular. The monitors accept higher resolutions so I can output in a wide screen aspect ratio however the image is not sharp because of the down conversion and maybe to some extent the resolutions might be high for the VGA connection.

I'd like the picture to not be squished but with the quality I see when I use the native resolution. So I need to send the monitor an image that's been stretched a little so the monitor can squish it back to the right proportions. I will be using an amd a6 apu fm2 socket since the motherboards for these still often have a parallel header making a mesa FPGA card unnecessary for driving the gecko stepper drivers for this build keeping the costs at a minimum and the setup simple. Do the ati drivers allow scaling independent of output resolution? Is there some way to configure xorg.conf to do this?

i need a bash script to switch to zero second on ac the waiting time for turning off the monitor (highlighten in red). same as for on battery (highlighten in purple)

Buongiorno a tutti
sono Oscar e sono nuovo del forum.

vorrei chiedervi aiuto per quanto riguarda una configurazione da impostare.

Ho un pc con linux red hat 6.3 dove ho installato 3 monitor.
ora il monitor principale dove mi vengono aperte le finestre è quello di sinistra (monitor 0) ma vorrei cambiare le impostazioni in modo da aprire sempre nel monitor centrale, o nel monitor dove si trova il mouse.

come devo fare?
grazie

Oscar

A little embarassed to even ask this, but...

In the last few evenings, a typical Linux session has been creating a root file system on an SD card, mounted on /mnt/sd2 (partition2 of card). At the same time watching a movie from the HD, mounted at /mnt/HD.

I was wondering if everything going through /mnt might be slowing things down at all. The answer should be 'no' since everything is mounted to 'root' and that doesn't seem to be a problem, but maybe /mnt is handled differently than root.

Just ran an experiment with 'top' and seeing what is happening with mplayer and debian bootrap:

Code:

5562 walter    20   0 62980  23m 9.8m R  38.0  2.7   4:01.75 mplayer
 1852 root      20   0 32048  12m 3728 S   3.0  1.4   2:08.92 Xorg
 2020 walter    20   0  276m  14m   9m S   2.0  1.7   1:32.03 gnome-mplayer
 2070 root      20   0     0    0    0 D   1.0  0.0   0:25.22 mmcqd/0

Can't really tell much from this, except that 'mmcqd/0' must be the bootstrap program unpacking things in the sd card. It kind of begs dumb question number 2: the unpacking process is crawling down the terminal screen, why is it not using more cpu to speed itself up? Must be the sd card can only accept writing to it at that speed, average about 1 second per package? Can't pull the card out at the moment, but pretty shure it's class 10, although suspiciously cheap from Eb.

I have installed CentOS 7. It was working fine until today that it hangs.

After several initial lines of ...driver cache write through...

it goes to the next black screen with a _ keeps flashing. I waited for 20 minutes several times but to no avail.

What is the problem?

hello, i have installed ubuntu one hour ago and i cant change my screen resolution. In displey options i have only two basic options: 1024x768 and 800x600. My monitor is has a resolution of a 1920x1080 and on windows it works fine. I havent checked third-party softwares when i was installing ubuntu and i think that i past by graphic driver(on windows i had ati control center). If anyone can help im using Gigabyte radeon r7 260x oc 1gb ddr5. I would realy love to change my screen resolution and play games.

OK, I fixed the issue with the download. I installed Linux Mint Cinnamon "Rebecca" 17.1 on the computer. It said it was installed successfully, but when I rebooted all I got was a black screen with the cursor stuck in the upper left corner of the screen. I let it sit for a long time (maybe 45 minutes), did a control alt delete but nothing happened. I had to shut down the computer manually.

Hi everyone,

I tried to install Elementary Freya and everything was good, though suddenly while using my laptop I get a black screen. I cannot use the mouse nor the keyboard. When I press the power button, to put the computer in sleep mode, and the open it again, I can see the desktop but cannot do anything.
I tried to use Mint 17.1 and then reinstalled Elementary again but I keep getting the same problem.
I use Linux next to windows 8.1

Thanks in advance, I would appreciate any help

Hi,

I have Kali linux and updated it a few days ago and now when I search for networks after going into monitor mode it tells me "no wireless networks found". before the update, monitor mode used to be "mon0" After the update, after entering monitor mode it says "wlan0mon" not sure if this helps. I use Wicd network manager but the origional network manager also cant see any wireless networks, it says "device not managed".

Thanks
