OpenSUSE :: Screen Blanker Modules Are Using Almost All The CPU Cycles?
Jul 22, 2010
I have a couple of question regarding the screen blanker on Gnome desktop.I used to use a 1024x768 display with previous openSUSE distribution. With 11.3, I discovered the new "auto-configure" X feature. The default screen mode was 1600x1200, but I changed it to 1280x1024.My gfx board is a Matrox G400 DH. Hardware acceleration is disable because of a missing mga_dri.so (fall back to software rendering).I find some screen blanker modules are using almost all the CPU cycles. Animations are very slow, and it can take long before a keyboard hit or mouse movement makes to leave the blanker.
So the questions:- Is there a way to define another (smaller) screen resolution just for the blanker ?- Who should I try to convince to add mga_dri.so back in Mesa again ?- When the monitor go to sleep (DPMS), the blanker still is running, uselessly consuming CPU times. (I can see that because at the first mouse/kbd event, the monitor wake up and shows the blanker running.) Is there a way to configure the blanker to stop running when the monitor is sleeping ?- There are some modules which load images from HD (not the diaporama which load images in ~/images). But the shown image is always the default built-in one. Where is the blanker trying to load images from ?
I have an installation of Maverick using command line only. It switches the monitor to standby after only about 5 minutes. Previous Ubuntu server and command line only versions do this too. Does anybody know where the setting is to change or disable this behavior? Perhaps something to do with ACPI?
Every account every option I try. when I login, it just cycles back to the login screen. I have attempted to do a repair install, but to no avail. it happens when I try to boot normally or if I boot into failsafe.
I was running 10.04 until yesterday, when it occured to me that I could upgrade to 10.10. So I went to Software Center, set it to get normal releases and left it to do its job. The upgrade appeared to go without a hitch and I rebooted. The login screen appeared. But just before I could click on my username and enter my password, the screen went blank and a second later the login screen was back. But then just before I could click... Undeterred, after half a minute of frantic clicking I did manage to click on my username and get the password prompt. This time, the login screen didn't go anywhere. Yay. To cut a long story short, this is now my standard logon procedure. However, the plot thickens. I appears that instead of 10.10, I ended up with 11.04, Natty Narwhal, which 'was released in April 2011'. If I download an .iso of Maverick and install it over my current version, will it leave my data unharmed AND reset everything so that it works again?
Basically when I add more than a single 2gb RAM module, my computer starts randomly crashing every half hour or so, the screen freezes with no response. I have tested the RAM with memtest 86+, it only happens when there is more than one module. The system is openSuse 11.2 64bit and it had a single 2gb RAM module when I first installed it, and removing all but this seemingly fixes the issue. The following is the error message I get when the system crashes, It seems to continue messaging after the initial visual lockup.
I don't know what the problem is, but from searching the web it could be a number of problems, the memory is not being allocated correctly or it maybe there's some conflict no between my ATI HD card/driver (latest driver from ATI repo).
I am running open suse 11.3 and keep up on maintenance. Ever since upgrading to 11.3 I find that the number of cpu cycles is being eaten for apparently nothing. In looking at the system monitor I frequently find that Xorg is using 24% and frequently more than that. What can be done to reduce the cpu cycles, or fix the problem?
I've been struggling with suspend to disk (hibernate if you prefer) for a while, it works after a fresh boot and for several days' worth of overnight hibernation as I go about my work, but eventually it stops working - it gets to the splash screen but the bar only makes it a little way to the left before stopping, and then after a timeout the system just returns to the "session locked" screen - no real error messages.
I've done my best to try to find out what's causing it to break but I'm really struggling, the suspend process doesn't appear to write anything helpful to the dmesg log or the /var/log/pm-suspend.log - the only thing that I've seen at about the right point in time is cifsd, but I can't be sure that it's a problem with cifs as hibernate continues to work immediately after mounting windows shares with cifs.
I was trying to install VirtualBox through the YaST > Software Management but it is not working, someone in the forum told me that I have to download the OSE version and do it manual way. Finally I am able to start up VB but not able to use the network connection. Thus I am trying to do this:
/etc/init.d/vboxdrv setup. I get this error:
[code]...
When I type dmesg, it shows me a bunch of info which I don't know what should look for. When I type modprobe vboxnetflt, I get the error: FATAL: Error inserting vboxnetflt (/lib/modules/2.6.37.1-1.2-default/updates/vboxnetflt.ko): Invalid module format. what should I do in order to get my VB to be able to connect to the internet?
I want set up VPN on my VPS but when i try to turn on tun/tap i see:
:/lib/modules# modprobe tun FATAL: Could not load /lib/modules/2.6.18-194.17.1.el5.028stab070.7PAE/modules.dep: No such file or directory os : debian 5 (folder lib/modules is empty)
I've been trying to load my pcmcia network card driver "xirc2ps_cs" at startup with no success. I have added "modprobe xirc2ps_cs" to the rc.modules file but it doesn't load at startup. Curiously, though, if I execute rc.modules AFTER the machine has booted it will load the modules just fine. Just not during the boot up process. Thinking that hotstart might have been causing problems I've disabled hotstart (chmod -x) temporarilly to remove it from the picture, but there was no change.
I'm trying to install Pystromo using both the README packed w/ the app, and this guide, both of which start off by instructing you to add a new line to the /etc/modules file.
However, there is no such file on Suse 11.2, at least not in that location. I assume there's a Suse version somewhere else, anyone know what it is?
Tonight I installed ubuntu 10.10 (32 bit) on an external usb harddrive with a dvd I burned and I used my older desktop. I disconnected all internal and external drives first so everything had to be put on the usb drive I selected (only option available). I used the option to load extra software, use the entire hard drive, and let the software do it's thing. I basically had no options where to put things and it didn't have much choice.
When I boot the usb drive on my laptop (win 7 64 bit) by telling the bios to boot to it first... I get an error: modprobe: FATAL Could not load /lib/modules 2.6.35-22 generic modules No such file or directory. This message appears twice and then it does boot into ubuntu and seems to work fine. I'm new to this OS so that is an uneducated guess but the things I have done seem to be working. So exactly what is this error referring too? Is there a way to fix the problem or do I just ignore it.
I have a machine running Fedora 14 and a bunch of movies stored on it as '.iso' images. It is connected to my home theater. I used to use VLC to play these movies and it worked great for a long time. About 4 months ago, about an hour or hour-and-a-half into a movie, the audio suddenly "disappears" and the machine goes CRAZY with almost 100% of the CPU spent writing to the SWAP. At first I thought the machine was locked, but it isn't; it's so doggone busy writing swap. I am unable to get enough cycles to terminate anything. I found the swap activity through System Monitor - it was ABRUPT. Sound stopped, machine became preoccupied with swap.
I have removed/reinstalled VLC, the machine has undergone a couple kernel updates, and I have removed/reinstalled a number of things associated with audio (CD ripper, mpeg stuff, etc.) yet the problem persists. I don't know what happened or when (update-wise). Any body got any ideas? While a solution would be great, I'd also be happy with a couple decent suggestions on what to look for.
I've somehow got it into my head that it's possible to share CPU cycles, though I've no idea where from.So basically that's what I'm asking - is it actually possible to tell one system to 'donate' it's unused CPU time, cycles, whatever they are, for another's use?
"Servers aren't meant to have GUIs because they are a serious waste of CPU clock cycles." I encountered this line from somewhere here in ubuntu forums, but how could I install tools like mysql wrokbench and stuff, w/c will make my life a lot easier as an administrator? or is there such thing as remote administration?
I'm planning on setting up a new Linux box expressly for distributed computing (BOINC, SETI@home, etc.). All things being equal, what's better- More clock cycles or more cores?
Yet another problem I have. Suse is taking a while to learn but I swear I'm getting there. Can pritty much do everything by CLI now. I'm trying to run VMware Workstation 6.5 on OpenSuse 11.2, Gnome. I had it running fine but then needed to do a system re-install and upon installation this time I get a error saying it's is Unable To Build Kernel Module and reffers me to a error log. The error log says:
Code: Mar 14 22:07:51.420: app| Log for VMware Workstation pid=6136 version=6.5.0 build=build-118166 option=Release
I am having some issues compiling kernel modules against the pre-built OpenSUSE kernel. Whenever I compile a module and try to load it, I get something like:
Code: insmod fs/smbfs/smbfs.ko insmod: error inserting 'fs/smbfs/smbfs.ko': -1 Invalid module format It doesn't actually matter what the module is, they all do the same thing. I have tried the above mentioned smbfs, I've also tried:vmware kernel module
I've got a weird problem since the update to 11.4: every time I use a yast module (the problem occurs with all of them), when I've finished (press OK or Cancel), it relaunch the module after the work is done. For example, launch the Package Manager, choice a package to install press OK : it performs the install and then relaunch the Package Manager. If you choose to quit, it will relaunch it... The only way to stop it to kill the process (or killx).The same problem occurs with the terminal version of yast. it's linked to a config file of yast under root or something so? I haven't found such problems reported on the internet.
I have 2 nvidia gfx cards, if I use the nvidia settings tool to view 2 monitors with the same gfx card works fine, when i use one gfx card for one monitor and the other gfx card for the other monitor X doesnt start and just cycles through monitor flashes.
Just trying to figure out some stuff with a broken process. A java app seems to sometime get stuck on a loop or something and i'm trying to find out what's causing it using just the following #sysadmin tools at my disposal.
Things like:- htop - find the PID thats causing the High CPU cycles. I'd then want to use /proc/[PID] or lsof -p [PID] or strace [PID] etc. But the PID doesn't exist in 'ps -ef' output so I think htop must be showing me kernel level thread PIDs?
Not sure about the PID's HTOP is actually giving me? I know that some of them are the real PID's that can be accessed through /proc/[pid] etc but others are not but are i assume child processes or more likely threads as child processes are normally shown in a default ps output anyway.
Is someone able to help distinguish to me about what exactly all these other PID's are that I can't manipulate or find apart from when using HTOP.
I've installed SLES 11 SP1 as a VM on my Hyper-V/Win2008R2, HP DL380G6 QuadCore, total 18GB RAM, 4GB assigned to the VM. The installation does not include a gui and everything works as expected. The hv-modules are visible but the systems freezes while I - backup the system with Symantec BackupExec 2010/RALUS - run an rsync from my physical P DL360G5 I have to powercyle the VM to reestablish a connection i.e. to CUPS by browser or to open a new session by ssh. Why SLES crashes on hyper-V or what I can do here?
This has got me stumped. I expected to do /etc/init.d/vboxdrv setup after the upgrade from 11.3 to 11.4 but the command fails. The log is (it seems to repeat so I only quote the final bits to make it fit into the wordcount limit):
Code: make KBUILD_VERBOSE=1 -C /lib/modules/2.6.37.1-1.2-desktop/build SUBDIRS=/tmp/vbox.0 SRCROOT=/tmp/vbox.0 modules
I haven't been able to get a working X11 environment on a Dell PowerEdge 1850. Using YaST without an X11 environment sucks particularly when you are trying to configure Apache. In addition, the Apache configuration files seem to have changed significantly since the last time I configured Apache on a SuSE Linux distribution. Where can I find good documentation on editing suseconfig files to ensure that I get the modules installed that I need for the collaboration tool that I'm installing?
