I have a 64bit computer with SUSE 11 installed. When I try to switch an user the computer or monitors go to powersave mode. The only way to power it back on is to restart by pressing the button in the linux box.
View 10 RepliesI have recently been experiencing some issues with the powersave on my computer. I had my computer set to put the display to sleep after 10 minutes and put the computer to sleep after 30 minutes. The screen saver also activates at 5 minutes. When I woke up my computer (hit the power button) the computer would sometimes tell me that it was going into low graphics mode. I had to reboot to get my x server back. I disabled the power save to fix the problem, but I would really like to have it back. My latest Xorg.log gives an error, but I'm not sure if the power save caused the problem (more below). I am running a computer with an Intel Integrated chipset.My questions:
What caused the x server to crash?Should I post a bug report on Launchpad? If so, how? (im a bit of a noob as far as bug reporting)How can I fix the problem?Xorg.log:
Code:
X.Org X Server 1.7.6

Slackware 13.1, on a Dell... Opliplex GX260... running XFCE4, as root. Stuff runs fine. However, the monitor goes to powersave mode after 10 minutes of inactivity. I've turned off power management in the kernel, in the app., have checked the xorg.conf, checked everywhere I can think of, can't find where this is being set. how I can turn this off?

View 1 Replies View RelatedMy linux workstation recently crashed. After rebooting, Linux (Red Hat 5.3) will not boot properly and automatically went into emergency mode or recovery mode i think. I can still see my /home/user/ and all the files inside.I boot from CD to rescue mode and tried mounting read-only the /dev/sd5 which contains the files in the crashed hard disk to try to copy out my files but mounting was unsuccessful (invalid argument). I checked the filesystem type using fsck -N /dev/sda5 and shows it to ext2. i tried to mount another known working hdd and was successful.
My question is why in emergency mode, the crashed hdd is able to be mounted automatically as read-only but cannot be done in rescue mode thru a bootable CD?Is there any special mount options used in emergency mode?I also cannot copy out in emergency mode booting from the crashed hard disk as everything is read only.
I need boot in emergency mode (not single user mode), from docs:

in red hat enterprise 5 it's ok, not in red hat 6.
I've stopped/killed/uninstalled all power related stuff like powernow, powerd, upowerd, acpid, gnome powermanager also turned off APM and ACPI support in bios. And after that I still have a problem: My display's backlight turned off after a long period of inactivity and there is no way turn it on. (Sometimes kill of Xorg helps, sometimes alt-ctrl-f1/atl-control-f7 however I need about half hour to get my backligh back). How to check I indeed removed all power related stuff.

How do I get into Single User Mode in 10.04?
The grub menu seems to be gone in 10.04, and the computer boots in 2 seconds. It's great that it boots fast, but there has to be some way to specify boot options?
/etc/default/grub says the timeout is 10, but that doesn't seem to be the case.

If I enter "init 5" command it boots to multi-user X11 mode without any problem.I checked inittab file and default line has id 5. So it looks OK. What else can be wrong?
View 15 Replies View RelatedI am running redhat ES 5 on a dell server and recently, I ran into a snag where I was able to reduce a partition (ext3) but could not run resize2fs (mismatch between physical and logical blocks (i never found a solution to this). In any case I decided to log in a single user mode (appended 'single' at the GRUB loader prompt) and now I am always taken to this single user mode every single time I reboot and can't seem to get out of it. I have tried init 5 (runlevel that the system is set to boot into by default) but that does nothing (no message on the # prompt).Of course, I have 2 problems here:
1) partition issue
2) cannot log out of single user mode.
My laptop is a unibody macbook and has an intel core 2 duo processor. The CPU Scaling Utility never drops below 1.60Ghz. Is this normal? Also. in the ferquency governors, powersave does not appear. Can I install it?

During watching video in Kaffeine the powersave will start and after 30seconds will switch my computer off. When I watch video in Xine I do not have this problem (screen saver timeout is set to 10 seconds). I have not found this option in xine-config.

View 2 Replies View RelatedTrying to set my cpu to Powersave using the CPU Frequency Scaling applet. When I set it to powersave, it goes back to ondemand on its own. On the earlier versions of Ubuntu, I used to be able to set it from the main menu: system>powermanagement, but with 10.10, I don't get that option. Is there any way that I can set it to powersave permanently? I was also able to set it with Ubuntu Tweak, but it does not have that option either.

I have a question regarding application/process execution and it's the following:
Is it possible a user application (which will regularly be executed at user-space) to be re-written as a kernel-module to allow the entire execution to be under kernel-mode (i.e. no system calls should be needed)? I am not saying that this is the right thing to do; I am just asking if it's doable.
I'm running debian lenny. Suddenly when I rebooted my system I was unable to login. I type root and the password and it tells me the login is incorrect.If I boot into single user mode, it accepts the password just fine. Looking in the /etc/shadow file, it appears to be fine as well.Running passwd to set a new password sets a new password just fine, i can login to single user mode with the new password, however, I cannot login at a higher runlevel with the password.
If I delete a password in the /etc/shadow file, then try to login as that user, it simply says "Login Incorrect" without even asking for a password.
Upon OS start-up Debian gives a choice, one is just simply start Debian, another line to start Debian, but with brackets (single-user mode). What's this for? And when and why do you need to use this?

View 2 Replies View RelatedI have installed firefox to a user directory (version 3.6.10) /cache/app/firefox.
I have installed java jre1.6.0_21 to /cache/app/java/jre1.6.0_21
I have symlinked /cache/app/java/jre1.6.0_21/plugin/i386/ns7/libjavaplugin_oji.so to /cache/app/firefox/plugins/libjavaplugin_oji.so
So, in theory, when I start firefox the plugin should be listed in about:config - wrong. I have lots of other plugins working just fine, but java is not listed anywhere.
I ran strace -F ./firefox >/tmp/output.txt 2>&1 (the -F is necessary as firefox plugins are now loaded in a forked process). Firefox clearly finds my plugin:
It clearly looks like the plugin is being found, opened, and the first 512 bytes read and possibly memory mapped. So why doesn't it appear in the list of plugins?
One clue could be that there's another older plugin lying in the default directories (and I can't change this, I don't have root, hence running firefox in user mode).
Though surely firefox is smart enough to pick the latest one and use that? Is there a way of turning debugging ON during firefox start-up so I can find a debug message that explains why the latest JRE 1.6 plugin is being passed over?
Few days ago, the server did not respond to a ssh request from a user at night. A user tried to check what went wrong with computer and tried to login from terminal next morning. As the computer was unresponsive, he somehow decided to boot it by turning the power off. To make the story short, the server rebooted; however, he can't login to his account. Actually, the server could not start some processes; but was able to ask user to enter his account username. Even though, he enters the correct username and password, server does not accept the request. I also could not login as root.
I just checked the server logs by booting it in single user mode. Here are some interesting lines:
Before the reboot:
irqbalance : can't balance irqs on a uniprocessor system: failed
After the reboot:
irqbalance : can't balance irqs on a uniprocessor system: failed
fsck:
fsck /: (this is repeated 900+ times)

I have successfully installed Debian on a Sparc Ultra5, 270MHz SparcIIi CPU, 384MB RAM, 40GB HD. However, once Debian tries to load Gnome (right before the login screen) the screen goes blank, and so the machine becomes unusable. I booted of the NetInstall CD, into rescue mode, and executed a shell, but apparently there is currently a problem when running nano from a live CD, so I can not edit the xorg.conf file when I boot the live CD. So, I would like to just boot the install into single user mode, but I dont know how. Currently, when the Ultra5 is powered on, it tries to boot with command "boot", so I hit "Stop A". From there I type "boot Disk1" to boot Debian normally. To boot from a CD, I would type "boot cdrom" So any idea on how I can boot from Disk1 in Single User Mode?
My only other idea is to hook up another monitor I have which may be able to deal with whatever resolution Gnome is defaulting to. However, Id rather just boot into single user mode.
What good does getting into single user mode do?And what's the basic purpose of it , i.e is it maintaining purpose???

This might be something related with shadow file.
