How to start. I know the problem is polkitd. But how can I analyse the source of the problem more deeply? Something is calling polkitd permanently, but how can I find out which process it is? My system resources are limited.
View 1 RepliesI will be switching to Debian soon and have been forming a large script with a vbox test system to automate my system configuration when I switch.
When I install lamp (Or basically it's equivalent packages) apache and mysql start up automatically.
I could just use update-rc.d to remove the autostart but whenever there's a security or feature update for the package the files get replaced.
In addition, for some reason the system thinks it's a good idea to autostart half a dozen apache2 processes at the same time, sucking up a good 150Mb ram when not doing anything. (Anyone know why?)
How would I stop my system from doing this? Could I "chmod 000" the /etc/init.d files?
I installed Debian 6 last night on an older Compaq. For the system to properly reboot and shutdown when requested, both acpi=force and reboot=warm must be in the boot parameters, this was required with other Linux distros installed on this hardware. Otherwise, the system erroneously shuts down when reboot is chosen.
I would like to know how to permanently add these so they pass each time the system is turned on.
I already added these to /etc/default/grub (and ran update-grub afterwards) and at the next startup, noticed they were NOT in the parameters when "e" was pressed at the boot menu.
So from a web server stand point if we start using swap for httpd or mysql its bad and performance goes down the drain. So would it be a good or bad idea to disable swap entirely?
View 2 Replies View RelatedI just installed Debian 8 (loving it so far) and everything its working right except for one thing: The monitor resolution!
I've got a LG 22 inch monitor and it supports up to 1360x768 but the display settings only shows 1024x768 as max resolution. Doing a little research i was able to get the desire resolution (1360x768) through the use of the tool "xrandr". The problem is that the resolution its not permanent and i need to invoke the xrandr script (i wrote a very basic "script" to set the resolution) on every restart or session logout and of course this is annoying. I've tried to use "crontab" to invoke the script on every restart but for some reason did not worked.
So, making more research i saw that apparently the correct way to set the resolution is by making use of "xorg.conf" but didn't quite get how to do....
Here's the xrandr script that i use:
Code: Select allOUTPUT=VGA1
MODE=1360x768
MODELINE=""1360x768" 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsyn$
xrandr --newmode $MODELINE
xrandr --addmode $OUTPUT $MODE

View 1 Replies View RelatedI just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

There is a folder in my home titled 'gtk-3.0,' which continues to reappear even after I have deleted it. The reappearance of the folder seems to occur after using lxappearance to change the themes. I will not be participating in the headaches of the switch from gtk2 to gtk3, just as I did not participate in the headaches of the switch from KDE 3 to 4. So the following are my questions;1. Is it possible to permanently delete the gtk-3.0 folder so that it can not ever reappear in my home? (And why is it appearing there anyway? Shouldn't it be hidden with a dot?)2. If I can not prevent this folder from appearing in my home, is there a setting I can use in Wheezy to block gtk3 libs and apps from installation? Presently, the only gtk3 lib or app shown by aptitude search is libcanberra-gtk3-0, but I can't remove it due to notification-daemon dependencies.3. If I switch from all gtk2 apps to all KDE apps will that solve the problem of gtk3 placing a completely unnecessary folder in my home?
View 2 Replies View RelatedAll my LC environment variables are currently set to POSIX at boot, though I can't find the startup script that does this. I've grepped through /etc/rcS.d and /etc/rc2.d but no luck. In /etc/default/locale, LANG is set to en_GB.UTF-8, which is my preferred locale. But this doesn't stop all the LC's being set to POSIX. Consequently, my dates follow the American convention, which I find hard to read.
I tried resetting with update-locale LC_TIME=en_GB.UTF-8. This changed all the locales to en_GB but only for the session. When I rebooted, everything went back to POSIX. The only change is that en_GB.utf-8 is now in the /etc/default/locale file as the value of LC_TIME as well as LANG.

I recently got an upgrade from my mobile broadband provider (3 UK) that included a ZTE MF112 modem. I found that (unlike the Hauwei modem that preceeded it) this item did not work "out of the box". After a bit of googling around I decided that a good starting place would be to upgrade the OS on my laptop. I've been meaning to do this for a while anyway so have just installed Squeeze (the i386 version, on Thinkpad x61). I think it's now pretty close to working "out of the box" but annoyingly isn't quite there. I thought of getting a ZTE modem to work say that usb-modeswitch needs to be used to make it not load as a cdrom. However, it appears to load correctly without any alteration (in fact, adding the /etc/udev/rules.d/zte_eject.rules file I have found described appear to do the reverse and make it load as a storage device - at least an icon for it appears on screen).
lsusb correctly lists it as device 19d2:0031 and identifies the device as a ZTE MF636 (though it says MF112 on the package). Looking at the Network Connections tool there is an entry for 3 mobile that is, afaik, correctly configured. If I click on the network applet on the toolbar, there is a bit of contradiction: towards the top of the drop-down list it reports mobile broadband as not enabled, but further down under the "available" list is an entry for "3 internet". I haven't paid too much attention to the not enabled entry because it also reports the wired network as not managed, so maybe this is just a quirk of network manager. - I know you have to comment out eth0 entries in /etc/network/interfaces to have network manager deal with the interface in Squeeze. There are no entries for the mobile connection in the interfaces file.
If I click on the 3 internet entry the applet goes momentarily into trying to connect mode (the circling dot) but very quickly pops up a Disconnected box, and that's all that ever happens. I note that the light on the modem stays permanently red. On the old Huwei it started green but went blue, and I think I read something about it also changing colour on the ZTE. On the other hand, the Hauwei didn't show up on the network manager list until the light had turned blue, whereas this does seem to be there. It looks as if the problem is something fairly trivial since the device appears to be both recognised and (almost!) correctly configured. How to sort this.
Is there any program for GNU to calculate CPU's performace in marks (should support multi-core CPUs)? So it will be possible to compare performance of different CPUs.

Just installed Sqeeze and works almost flawlessly on my Clevo w870cu. My machine has a realtek wifi card so I installed the vendor specific driver (see below). Wired performance is super, wireless performance however is very bad on Linux. On "Windows 7" (dual-boot, which I never use, only in these cases to sort out problems...) wifi performance is slightly better. My smartphone's visual wifi-analyzer (I couldn't find a Linux equivalent...) showed good signal strength (aournd -50db a 4 m distance from router) an little-to-no interference from neighboring channels.

Is there any way of improving performance with the GTX 470 using Wine software with Debian Squeeze?
Installed version of Wine is 1.3.6 tested with different versions of nVidia drivers including the latest one, still VERY slow performance and many quality settings are in red. Setting WoW to use OpenGL improved the performance, but deactivated many quality settings in red, unfortunately. Looks to me as it's using lower features than OpenGL 2.0?? So what's up with that? GTX 470 supports OpenGL 4.1 so I suspect it's an limitation in Wine software, can anyone confirm this?
Default kernel 2.6.32 is used in all of this. The computer is an Intel Quad at 2.4ghz + 4 GB DDR 2 or DDR 3 memory.
Does anybody know more tips and tricks to increase visual performance besides these?:

View 2 Replies View RelatedI just have a few questions about LVM and RAIDs. It seems they are basically the same thing. Is this correct? I can add two drives together on both of them and it appears as a larger drive, along with other setups like raid1 and raid5, etc.. And is there a difference in performance between them?
And my second question.. I know one is stripped and one is not, but is the performance between a raid1 and a raid0 the same? I've been told that raid1 is faster than raid0 because the data is written twice.. and therefore can be read from two different disks which equals faster read speed, but slower write speed since it writes to the two.
II installed flashplayer by every different method I can so far, and all of them have the same problem. This problem presents itself, for example, while playing a video on ...... As the video loads, flashplayer is fine, but as soon as it starts playing, the browser tab begins to run at roughly 1 frame per 10 seconds. When I turn the browser priority to maximum in System Monitor, it improves slightly, going to about 1 frame per second. The strange part is, my CPU and memory usage barely spike at all, to less than 30%. This happens regardless of browser (have tried iceweisel and chrome). It happens with hardware acceleration on, and off. I have tried installing flashplayer from the tar.gz on the adobe website, from the repository (all three packages), and manually placing the plugin in the browser myself. The issue presents itself the same every time.
My system specs are: 1.83GHz duel core intel centrino processor, 3GB RAM, ATI Mobility Radeon HD 2600. Nothing fancy, but flash player performs as flawlessly as flashplayer can under windows (and also performed well in my previous Ubuntu 10.04LL install).
I have 2 ASUS Boxes (one with 8GB, one with 4GB) When both mtus are set at 7200, using scp to copy a 56MB file takes 2:06. If I reduce either mtu to 1500, the speed is 2 seconds. I'm wondering if this is some kind of kernel bug or driver bug or what. For the moment, I've lowered the mtu to 1500 to get the performance out of the machines, but find it interesting that what should make it faster is actually slowing down. Where should I post this to get it looked at? Is anyone else seeing it.I see a similar performance issue with smbclient too.

Now,the problem is back, even though I made the same setting in the boot loader.
View 14 Replies View RelatedMy last laptop was replaced (I gave it to my step-dad, his laptop broke and I bought myself a new one).
I am running Squeeze (as I was on my other laptop) and everything is fine except for the games. On my other laptop games like OpenArena and Warzone 2100 ran perfectly fine, but on this laptop, they are impossible to play. The game will open, but everything is so slow and choppy that it takes a couple of minutes to even move the cursor to the exit game buttons.
My current laptop is an HP ProBook4525s with the current specs:
AMD Athlon Dual-Core P340 2.2 GHz processor
2GB DDR3 RAM
ATI Mobility Radeon HD 4250 Graphics Card
I'm not sure what other information to put here, I've tried searching how to fix this and most people say to lower the resolution and details for the games but that doesn't work, heck, even Tux Kart is too slow to play!
When I installed squeeze I was informed that I didn't have the rtl8168d-2.fw firmware for my laptop, I'm not sure if that helps here at all (can't seem to find what it is for, the only things that google gives me are very technical with fixes that involve re-compiling the kernel).
I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?
i had recently loaded squeeze and had an issue with the 2d performance.i.e when being prompted for the root password, the shading slowly draws down the screen several times before stopping at the final darker shade. i then added the linux-firmware-nonfree package. all worked extremely well, even compiz, but i don't really care about compiz. i just loaded it to see how it performed. i then distro-hopped a bit and when i came back to squeeze the first thing i did was add the package, but the video is acting like i haven't added the package. i've searched for an answer, but have not found anything recent to indicate if xorg was upgraded or what.stable lenny works fine, but i'd rather have the nice console fonts when not in x and more up to date apps like gimp and xsane in squeeze.
