I had the problem that suddenly my screen went black after a period of time. It must have been ten minutes. The problem was, that I could not disable the behaviour by the means of the GNOME tools (screensaver or energy preferences). Stupid Linux.
And if you find this, you probably have, because I left this hint for you. 😉
If you have the same problem try this. First see if you got the same:
xset q |grep blanking
See of it looks like this:
timeout: 600 cycle: 600
If so the number in the left says something about the timeout of the screen in seconds. 600 seconds are ten minutes.
For the current session you can just type
xset s 0
If you just type in “xset” it will list some screensaver related commands t the bottom of the output.
The “xset s 0” disables the timeout counter and so effectively prevents the blanking of the screen.
I have no idea why there seems to be now no interaction between the GNOME tools and X11? I had this problem for months. I had played with “xset -dpms” bit this did not help at all.
Many of us do not have a xorg.conf any more, because we learned that autoconfig mostly works. But now this does not? Well I have added a xorg.conf withonly this content to the coniguration directory /etc/X11/:
Section "ServerFlags" Option "IgnoreABI" "True" Option "BlankTime" "0" Option "StandbyTime" "0" Option "SuspendTime" "0" Option "OffTime" "0" EndSection
This should be it!
Honestly this kind of shit fuels my doubts about some free software developments. Personally I can wait for some months to solve a problem. Now I usually don’t do reinstallations of Linux to fix things, unless I have a very serious issue. And I recommend to act similar. I think for most desktop machines updating seldom and be patient in fixing is the best way to keep a stable system. Sure not updating can lead to some security issues. But in my whole computer life I have not a single serious security issue. On the other hand I had thousands of problems with updates of software. So for most users the thing that really will cost you a lot of time is updating if you dont really need it.
I think the whole Microsoft/Windows shit has led people to believe that updating to the latest version is the best way to keep your operating system safe and stable. That might be very true for Windows. And it might also be a very good idea for internet servers. But on a generic notebook I would rather recommend to only install the software you need and stick with it as long as you can. What security risks do you fear? Somebody shutting down your system? Or somebody steeling your data? I guess your risk as a Facebook users is much higher that people steal your data that you just submitted.
Sure there might be people who need a lot more security. If you have important company data on your notebook and sit in an airport lounge connecting to a wireless LAN you better have your disk encrypted as well as your connection. And there is a slight chance that somebody can break your system because you are using your Openoffice.org has a security leak. But still my guess that chances of this statistically are very low.
Personally I would tend to use OpenBSD for a notebook, which is more safe by default, especially for people who don’t want to invest much time in keeping a system safe. And I guess it’s a very good idea not to connect to a WLAN at all if you are really worried about security. But nowadays people want to have it all and at the same time they want zero risk. My guess, but I am not a security expert, is that this is impossible. It’s like you buy expensive outfit to protect yourself from being robbed – but then entering the darkest parts of a city often. You will be robbed, even if you feel well prepared. The best way for not being robbed is to avoid some areas .
Ok don’t take that too seriously. There is never a 100% security. My point was, that it’s also a question of how probable a risk is and what could happen as the worst case. Many people don’t have important data, but more people need to have a computer which works when they need it. Strangely many friends I know tend to risk the functionality of their computers while they worry a lot that the might be at risk. So that’s why I get called for help each and every time and need to fix what some updates have corrupted.
