Do you use Opensuse 12.1 KDE4? Do you have a screen that blanks out after 10 minutes of no activity? Do you want/need it to run longer?
If you do this How To is for you.
If 6 six hours is good enough for you then this is what you can do:
- Click Kickoff
- Select Configure Desktop also called System Settings
- Select Power Management
- Select Power Profiles and set it like so: http://dl.dropbox.com/u/10573557/SUSE Misc/powersettings.jpeg If you want the full 6 hours just set yours to 360 instead of the 310 shown.
Setting up the Power Management this way should get you that 6 hours before it goes blank.
But what if you have just downloaded the entire Lord Of The Rings trilogy and you want to watch it on you PC or you’ re someone that has their PC hooked up to their TV?
That’s going to entail a few more steps.
The first thing that needs to be done is to reset the power conserve in the Kernel it’s done like this:
1) Change the the boot grub menu.lst by pressing the Alt+F2 keys
2) This will bring krunner at the top of your screen
3) Type this into krunner : kdesu kwrite /boot/grub/menu.lst (that .lst is L not the numeral 1)
4) You’ll be prompted for your root password give it that’ll get you the Dolphin root filemanager
- Find the line that looks something like this:
kernel /boot/vmlinuz-3.1.0-1.2-desktop root=/dev/disk/by-id/ata-WDC_WD3200AAJS-22B4A0_WD-WCAT10139735-part2 resume=/dev/disk/by-id/ata-WDC_WD3200AAJS-22B4A0_WD-WCAT10139735-part1 splash=silent quiet showopts vga=0x317
6) Change this line so that it reads just like this:
DEFAULT_APPEND="resume=/dev/disk/by-id/ata-WDC_WD3200AAJS-22B4A0_WD-WCAT10139735-part1 splash=silent quiet consoleblank=0 showopts vga=0x317"
7) Save the file close
8) Next change /etc/sysconfig/bootloader Press Alt + F2 & get krunner again type: kdesu kwrite /etc/sysconfig/bootloader
9) Find the line that looks something like this:
DEFAULT_APPEND="resume=/dev/disk/by-id/ata-WDC_WD3200AAJS-22B4A0_WD-WCAT10139735-part1 splash=silent quiet showopts"
10) Add this consoleblank=0 with a space after showopts make sure that the “ is at the end so that it reads like this:
DEFAULT_APPEND="resume=/dev/disk/by-id/ata-WDC_WD3200AAJS-22B4A0_WD-WCAT10139735-part1 splash=silent quiet showopts consoleblank=0"
11) Save & close
Now after all that this is the 2nd part
1) Kickoff>System>File Manager> File Manager-Super User Mode You'll be prompted for the root password
2) You'get a file manager like you did with kdesu in krunner once you have the Super User file manager
3) Click Root
4) Select the etc folder
5) Find & open the x11
6) Find the xorg.conf file select it then
7) Right click select Open with kwrite
8) Find the Section “Server Layout”
9) Add these lines to it:
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
10) Save & close
In the event you don't have a xorg.conf file
