Ubuntu :: How Do Settings Get Applied Instantly
May 7, 2011
I've been a Windows user for many years. I began using Ubuntu/Linux only recently.I noticed that on Ubuntu, all manner of setting changes get applied instantly. In CompizConfig Settings Manager, for example. Almost everywhere in Ubuntu, settings seem to apply instantly, without having to click an Apply or OK.
I wonder how that is possible. I have never seen that in Windows. I tried searching for an answer on the net, but got nowhere. Can anyone give me an answer? I'm not looking for a technical answer. Just wondering if it is specific to Linux/Unix.

I am running into an issue where the configured theme is not being applied when my laptop is started when on battery power. After it starts up If I navigate to Preferences->Appearance the configured theme will be enabled. This only happens when starting on battery. When plugged into AC it starts up fine and the configured theme is loaded.

I updated one of my x64 notebooks that has been offline for about a week. There were several updates needed. Towards the end of the update I got a message something about could not complete update because one of the updates was waiting for another process/update to complete.
I verified that it was still trying to update by opening terminal window. After I closed the info box which had a white minus sign it it and reran to check for updates, it said everything was up to date.
How can I be sure that the update in question was applied? Unfortunately don't remember which one. Is there a checksum run at the end of the updates to unsure the update is properly applied? All seems to be working fine.

The theme I have chosen in Ubuntu 10.04 (Ambiance with buttons in the upper right-hand corner) is not applied to the menu bars at boot/login. Menu and title bars should be very dark with a white font. When I boot the computer, the application title bar is correctly formatted, but the main menu bar of gnome and the menu bars of all applications are black font on gray background. When I open the theme selection (in German Einstellungen | Erscheinungsbild, in English likely something like Preferences | Appearance).
The correct theme is applied to menu bars without that I have to select the theme again; simply opening the Appearance dialog suffices. First I did not name my modified theme (showed up as first theme in the theme selection dialog, user modified). In trying to solve the above issue I gave the theme a name, but the strange behaviour persists. Where I can make the theme automatically and completely applied at boot.

I am running Squeeze AMD64 and install updates every couple of days. I installed the latest batch yesterday and got a "restart system" message, so rebooted. The usual messages scrolled past for a while, then the screen went blank, and that was it. I tried a couple of times with same result. I booted into maintenance mode to try to find the cause of the problem. Looking at /var/log/messages there is some strange activity going on. Unfortunately I can't easily paste the relevant portion of the file into this posting as the network isn't working (I am posting this from a laptop), but roughly what I am seeing is this:
PGD <some stuff>
CPU 0
Modules linked in: <long list of modules>
Pid, 1841, comm: Xorg Not Tainted <some stuff>
<about 20 lines of assorted values>
--[end trace <long hex number>]
and this repeats several times (presumably stopping when I hit the reset button). Sometimes it's CPU 0 and sometimes CPU 1, it mostly involves Xorg in Pid line, and apart from the first instance mostly reports Xorg Tainted.
I could just reinstall but would rather repair as it would be both quicker and more instructive.

That application is included in CentOS default repo and can be installed via yum. The version number indicates that this is a rather old release. This fact in itself is okay with me. But according to the original developer's site this release contains a major security bug and should be patched immediately. is the file from CentOS repo a copy of the original release or are any patches applied?

I was using firefox 3.X (latest) until recently but it irked for two reasons:
- it takes forever for everything
- it kept crashing (as in really really often)
first I got rid of some extensions to save some thinking energy, but didn't help much, so I downgraded and am now running 2.0 silly thing is, none of my extensions work - they seem to be 'registered' to FF3 (which I purged) This also applies to new addons installed from FF2.

I looked at the security adviseries page on slackware.org, and noticed only 1 listing for 2010. I'm currently using alien bob's slackware-current script to make a dvd iso (x86_64.) So is this patch already applied or what? How do I go about maintaining a secure system from here? I've tried to search for clues about this but I'm a little confused (very new to slackware,) so I apologize if this question has been answered many times. Also, when a security advisery arrives, do I need to download the updated package? Or can I simply find a patch from a single source and download / apply them? What would you do concerning this issue? I guess easily applying security updates is where debian shines. I'm really starting to like Slackware though, I must admit.

It's really weird, some applications simply don't start up. Skype for one, just shuts down before logging in, and Calibre shuts down instantly, when I try to run it. I've tried to remove and re-install it, but that doesn't do any good.

I use Slackware64 Current and since a few weeks, X doesn't automatically apply the native resolution (1680x1050) of my LCD screen, instead it uses a resolution of 1024x768.Since I bought this monitor in 2009, It had always worked as expected, and it's only since lately that I experienced this problem.After X has started, I can change the resolution through the kde tool but after an X restart everything is forgotten. Apparently, the correct resolution is detected but it is not applied.
My monitor is HDMI1.I don't use a xorg.conf file as it had always worked well this way, so I would like to track down this regression.I have an intel GM45 chipset.I have tried Mesa 7.9 and 7.10 in case.

I installed Ubuntu 10.04 LTS x64 on my laptop about a month back and I have been very, very pleased with its maturity and stability. However, I have seem to have hit a snag with my ventures into desktop Linux: I also dual-boot Windows 7 Professional x64, and it seems that every time I run Ubuntu 10.04, Windows 7 will immediately bluescreen on boot, reboot, and then be fine. I'm not sure what kind of harm this could be doing to the system, but it strikes me as very odd, and it's something I would like to resolve.
I have suspected this may have to do with mounting NTFS drives under Ubuntu, because my Windows OS and all of my media is stored on NTFS partitions. Needless to say, I would really rather not change this, because NTFS seems to be one of the few filesystems with large-file-support that will run with ease under Windows and Linux.
I have tried removing my main Windows 7 OS partition from the fstab in Ubuntu to see if that made any difference, but the problem persists. Could a secondary NTFS media partition mounted in Ubuntu really cause these sort of issues?

A weird problem arose a few months ago in my box and has plagued me ever since: the PC immediately reboots whenever I try to suspend or hibernate Ubuntu. It's actually instantaneous, as if I pushed the reset button.Way more days into googling than I wished I had to, I have tried just about every solution related to suspension/hibernation problems,but none really applies to the exact situation I'm experiencing, since most are about being unable to resume after suspending/hibernating, and in my case it seems the system is instantly killed and therefore doesn't even start said operation.
After rebooting, applications behave exactly as when the PC is hard-reset, which I think is an indication that running processes aren't being properly terminated and the system is just going down abruptly (if the less-than-a-second it takes to go down and restart the boot sequence isn't obvious enough).Before you ask:
everything was working fine before;
upgraded to Maverick but the problem remained;
every suspend/hibernate method that I know of (GUI, CLI) does the same;
can't easily test in another OS since I only have Ubuntu installed (no dual-boot or the like);swap partition is larger than RAM; /etc/initramfs-tools/conf.d/resume is pointing to the correct swap UUID;
tried several SUSPEND_METHODS and video-related options in /etc/default/acpi-support;
enabling/disabling the acpid and acpi_support services in BUM (Boot-Up Manager) has no effect;
enabling/disabling BIOS STR (Suspend-To-RAM)-related options has no effect;
unsetting NvAGP or setting it to 1 in /etc/X11/xorg.conf has no effect;
adding/removing the agpgart and intel_agp modules to /etc/modprobe.d/blacklist.conf has no effect;
installing the hibernate package has no effect;
not sure what I'd be looking for, but nothing strikes me as relevant in /var/log/messages.
This is really strange. May it be a hardware failure of some sort? What else can I try to work this one out or at the very least understand what's happening?

I installed openSUSE on my notebook with an usb drive using openSUSE 11.4 KDE LIVE iso. The installation process set the name to "linux-ygrl" which I don't really like. (I probably just missed the setting during the installation.). I tried to change it through YaST -> Network -> Hostnames and I set everything where needed to the new name and restarted but the changed weren't applied. I searched the web and found out about the /etc/HOSTNAME file which still contains "linux-ygrl". Now I could change it manually but I was wondering if there is a GUI for it? (I mean, openSUSE has for alsmost everything a GUI.

I am looking to install a c++ compiler. I run 11.4, and was told to look in the Software Manager for easy installation. I have no repositories installed, as the repositories in the Application sticky only applied to Suse installations through 11.3. I found the package "gcc45-c++" (Version Number 4.5.1_20...208-9.8) when I searched the Software Manager. I proceeded to install it, and had no problems, but when I looked in "applications", the compiler was not there. I'm aware that I may be revealing some great ignorance here, so I'll ask, should gcc appear? If not, how do I execute the program?

Evolution was working properly but now whenever I try to open it the program opens, flashes up on the screen then disappears. If I click on the little envelope at the top of the screen I can get both the compose new message screen and also the contacts to open, but not the main mail program. If I open the contacts screen and click on the mail button to switch to it that way, the program instantly disappears again. I have also tried applications/office/evolution but that has the same result.

I have two machines running Debian Squeeze (a laptop and a desktop). On my laptop sudo works fine, however on my desktop sudo doesn't remember my password for 1 second!!! I have created a script for the upgrade procedure with apt (to make things easier). The script is nothing more than a few commands separated by operators. It is completely useless if I have to enter my password six times while my script is running.
I tried to add timestamp_timeout=15 to the sudoers but it didn't help.
Does anyone have any idea why this could be?

New build of Slackware 13.1 x86_64 in Dell E4310 laptop. The stock install works fine barring a few bits of hardware but after recompiling the kernel X loads and immediately freezes, whence I need to soft power down (I cannot switch back to a console). On capturing stderr from the command line, when executing startx I get various warnings including:(polkit-gnome-authentication-agent-1:2368): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failedCan't really tell if the above is relevant... Sorry I can't dump the lot because the machine isn't on the net yet.
There is nothing errorwise in the Xorg log after a reboot. The very last line relates to a video mode with modeline info etc. I have compiled either into the kernel, or as modules everything I think I need though unfortunately I seem to have to load them all manually, so I hav no idea of I've missed something important. This includes all the Intel drivers i915, drm, intel_agp etc.Googling suggests bugs with polkit and I don't know why gnome has anything to do with my system in any case.Other thing that I find annoying is that xorg.conf no longer exists and I am relying on the HAL daemon, about which I know nothing. It took me ages to find how to change the X keyboard map - very frustrating. How do I confirm which video driver etc.?

For the last 4-5 weeks my cpu will suddenly turn off, not shutdown, just instantly go off.
It has happened when I've been browsing and even when I have not been at the computer. I know it could be a hardware malfunction, but I started seeing some consistency in it's crashes the last two weeks.
During Skype, more and more, it would crash. And then I whenever I would upload more than 3 MP3 files to Amazon Cloud Music Player It would crash in the same way.
I downgraded off Tumblweed this morning and it seems to be working better. It has crashed once, but it completed uploading 12 tracks to Amazon, which it had not been able to before.
I'm running KDE 4.6.3 currently and Firefox 4.0.1 with Skype 2.2.0.25-suse111. I was using kernel ..39, now I'm on ..37.
I'm content to stick with the 11.4 repos and ..37 kernel. But I would love to hear if anyone else has had these issues, or a suggestion to solve this?

I am looking for some easy to use cross-platform audio software that can send live audio from my Windows XP PC to other computers (laptop/netbook/MID) in the network. Mine MID is Meamo Linux device. When I mean audio, I talking about whatever is coming out mine PC sound card at any point (music, video's audio, XP sounds clicks, etc). Also, the audio MUST BE live, aka no delay between between computer.Basically, the idea to is to "send/stream" audio to other PC over wifi/network so all the sounds are sync. Sort of like a whole house audio system, but one that uses computers so I don't need to buy any additional equipment. Also, it would be nice if the client software worked on other OS, like Linux.I have been looking some software solutions with no luck. I tried UPnp (shoutcast/Icecast) servers, however all of them have 1 Sec to 10 second of delay.Again, I am looking for something instant.I have also looked at pulse audio, however the setup seem too complicated for Windows especially.

I'm trying to install Debian 6.0.1a (64bit) onto a machine that had Debian 5.08. It freezes up almost immediately after loading the kernel. The last line, about 2.6 seconds in, is where it found a SATA drive. (There are two SATA drives). This is a Tyan S2912 with Opteron 2347HE. It seems to be kernel release related. I tried the 5.08 disc again, and it works OK.
With other distros, such as Opensuse and Ubuntu, I have the same problem. The newer releases freeze up almost instantly after loading the kernel. Am I stuck with IDE drives or older kernels? I wanted to try something newer as the fonts in the 5.0.8 release were barely legible. It gave me nauseating headaches within a couple of hours of looking at it. My wife couldn't stand to see it when she came by. I've tried every bios setting change I could think of without a solution.

I just installed 5.6 using the x86_64 netinstall - all appeared to go well, albeit a little slowly. At the end of the install i rebooted the machine but CentOS won't load. If I select the CentOS option from grub (only other option is 'other') the machine instantly reboots.
Only options selected for install where 'server' and 'server gui'.
Editing the CentOS options shows the following but I've no idea whether this is correct or not (assume it is):
root (hd1,0)
kernel /vmlinuz-2.6.18-238.e15 ro root=/dev/VolGroup00/LogVol00 rhgb initrd /initrd-2.6.18-238.e15.img

I have recently had problems a with Movie player. It seems to having trouble playing DVD's and video files. it has a tendency to stop/freeze and sometimes if I try move the progress bar or scroll back or forward it wil just instantly close the Movie Player. I'm wondering is there a way to check it for bugs or is there a more reliable/better quality player that I could get instead.
