Ubuntu :: Prevent Applications From Changing Monitor Resolution?

Jul 7, 2010

Sometimes when starting applications, especially with Wine, the screen resizes to a much lower resolution. Sometimes when I close the application & usually when it crashes/I have to kill it, the screen stays at that much lower resolution. To get my normal 1900*1200 resolution back I have to delete all the applets I've put in the top menu bar to for there to be enough space for the menu to appear for me to select System>Prefs>Monitors.How can I prevent an application from altering my resolution & just force it to run windowed, or at a higher resolution?

Ubuntu Multimedia :: Changing The Screen Resolution In 9.10 Samsung Monitor

Jan 27, 2010

I am running Ubuntu 9.10 on a new HP PC (Pavilion p6240f PC).This came with an Intel GMX X4500 Integrated graphics.My monitor is Samsung SyncMaster 2333. Initially I got a very bad resolution, Later I edited /etc/X11/xorg.conf (created the file) and added the following.

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 30 - 75
VertRefresh56 - 61
EndSection

[code]....

With both 1600 x 1200 and 1680 x 1080 I get the resolution but I see lots of shadowing.(The letters are not crisp) Do I need to upgrade any driver ?

~$ lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)

Ubuntu :: Changing A Display Resolution If You Have A Higher Resolution In 9.1?

Dec 7, 2009

I searched the archives and didn't find anything on this, and was just wondering if there is a problem if you load Ubuntu 9.1 and have a display that's higher than 1024x768. I'd prefer a machine with a higher res, but I've heard that Ubuntu will only go as high as 1024x768.I'm guessing, however, that by 9.1, it should recog the higher res while loading and it won't be a problem, but thought I'd check before shelling out on a machine with a nicer display.

Ubuntu :: Prevent Users From Changing Their Password?

Jul 17, 2010

I use the following method for preventing the users from changing their passwords , is there any other method other than this ?

ls -l /usr/bin/passwd
-rwsr-xr-x 1 root root 37140 2010-01-26 12:09 /usr/bin/passwd

so we need to remove the suid for that command as follows :- chmod u-s /usr/bin/passwd now normal users won't be able to change their own passwords - and only the root user will be able to do it for them.

Ubuntu Security :: Prevent Users From Changing Settings

Jun 15, 2011

I am administrating a system with about 40 or 50 users, and we recently jumped ship from windows to ubuntu. Most of my users are getting along fine, but it seems every few days, i have to help someone who accidentally changed something, and now their account (or more rarely, the machine) is unusable, and has to be reset.

I know configuring /etc/sudoers is a huge step toward fixing my problem, but that still will not completely solve it. What I would like to do is prevent users from making ANY changes to the system (aside from their work files and the like), including themes, icons, desktop, background, etc.

Red Hat :: Prevent Kudzu From Changing Ifcfg-ethX File?

Aug 31, 2010

Running Centos 5.5 64bit. Sometimes I boot this instalation in real machine, sometimas using vmware workstation. The problem is that these environments have different network interface cards - as soon as kudzu detects that network device changed it renames ifcfg-eth0 to ifcfg-eth0.bak and places new default ifcfg-eth0.

Is it possible to command kudzu to leave ifcfg-eth0 as it is ?

Ubuntu Multimedia :: Prevent Applications From Resetting PulseAudio Settings?

Aug 26, 2010

Ubuntu Lucid, Asus T101MT tablet netbook.

Background Info: Normally the microphone doesn't work with some applications such as Empathy or the new Google Talk plugin for Linux. The workaround I'm using (and I don't know why this works) is to unlock the left and right channels in Pavucontrol and set one channel to zero, and to boost volume I set the other to max.

Issue: The Google Talk plugin is resetting the channels to be locked together. This is pretty frustrating because now they have free calling and I have no cell reception in my dorm room.

Fedora Security :: How To Prevent The Appearance Changing Window Running

May 21, 2009

I want to prevent users changing the wallpaper, as i couldn't found any direct method I thought of preventing the /usr/bin/gnome-appearance-properties being running,

I know that the user also can set the wallpaper without running that . But didn't found any other way .

I tried to use SELinux to it and I'm stuck at writing a own policy.

According to SELinux, it prevents everything ., but as i have mapped the user to a SElinux user ,even though he can use administrative tasks , he can run the appearance window. that means he has got the permission from a different policy , Currently I'm stuck at this place.

Suitable way to prevent the wallpaper being changed by the normal users.

Security :: Prevent Users From Changing Or Unset Their HISTFILE Variable?

Sep 30, 2010

'readonly HISTFILE'

but the user could tamper with the histfile itself. Like:
rm -f $HISTFILE;
rm -f $HISTFILE; mkdir $HISTFILE;
rm -f $HISTFILE; ln -s /dev/null $HISTFILE;

I'm experimenting with PROMPT_COMMAND to execute a command each time the user executes a command and so log it somewhere else.This post was pruned from the 2009 Is there a way to prevent users from changing or unset their HISTFILE variable? thread. Please do not resurrect old threads but instead create your own (and maybe provide a link to the old one).

My display still goes to sleep and I am prompted for my password when I leave the computer unattended.

I would like to be able to hit the "Lock Screen" app I added to the top panel to lock my screen, but otherwise I would like it to just stay on.

Fedora :: Prevent Some Apps From Appearing In Gnome 3 (Activities->Applications)

Jun 11, 2011

I don't want to install alacarte to do this. I've copied the .desktop files from /usr/share/applications to ~/.local/share/applications that I don't want appearing in the gnome 3 applications list (e.g., email settings for evolution), and added 'NoDisplay=true' to the end of each desktop file. Restarted gnome shell, even tried logging out and back in, but they still appear there. Previously, in gnome2, desktop files under the home dir superceded the global directory. Do I need to edit them directly as root to effect the changes, or could this be a selinux problem?

Ubuntu :: Changing Console Resolution Without Vga Parameter?

Mar 4, 2010

Let's start with some context: About a week ago, I saw in the university computer that the text mode consoles(ctrl+alt+f[n]) worked with a great resolution on a 19" wide screen (I think it is 1440x900) running fedora 11. So I wondered if I could make the text consoles at home to work with a good resolution also.So I started to search for that and found the kernel parameter vga= . The problem: it doesn't support 1440x900 or any other 16:10 resolution for my graphic card. Then I thought that maybe fedora uses some module that allows that, because the livecd allows a good resolution (by default) on my desktop computer.

What I thought so far is that fedora is not using vesa for the virtual console (which i think is the driver that ubuntu uses) and I want to know what driver it is and how to use it in ubuntu (either compiling the kernel or simply installing something).I don't even know if my guesses are right or not. But I've gathered some info so far:From /var/log/messages (fedora 12 livecd) I got this part, which I think is the really interesting one.Quote:

Mar 2 22:37:18 localhost kernel: [drm] Initialized drm 1.1.0 20060810
Mar 2 22:37:18 localhost kernel: [drm] radeon defaulting to kernel modesetting.

Ubuntu :: Changing The Grub Menu Resolution?

May 12, 2010

I'm using lucid x86_64. I tried changing the grub menu resolution and it works fine on 1024x786 and 1280x1024 but since my monitor is a widescreen lcd i tried the native resolution which is 1440x900 which gives a message "Frequency out of range" during boot after bios post. but then after 10 secs ubuntu boots w/o any problems...also I get the same problem with 1280x800 so i'm guessing it doesn't support wide screen resolutions...is there a workaround?

Ubuntu Multimedia :: Changing Resolution For Usb Camera?

May 22, 2010

I've been having a fit with Ubuntu (even tried updating to the new version). I have a USB camera (1.3mp- 1024x768 ) that I need to observe and capture images with (microphotography). I've downloaded and installed multiple packages, but have not found any way to change the default resolutions for V4l2. The resolution closest to what I need is 1024x816, but the video is torn and unusable. One program, Kamoso, worked fine in 640x480 mode, but as soon as I upgraded to Ubuntu 10, it went to the higher resolution (1024x816) which doesn't work right.

Is there some way to force v4l2 into a 1024x768 mode? The camera is a Tucsen 1.3mp microscope camera. I've emailed the company for more information and to see if they would email me the software/drivers (I lost the driver disk in a fire), but nothing so far from them.

The programs I've installed and tried: Camorama, Kamoso, Xsane, Cheese, VLC media player, v4l2ctrl, v4l2ucp, v4lctl, v4l-info. Camorama doesn't work, Kamoso- you couldn't change resolutions (ditto for Xsane), Cheese - I can change resolutions, but they have these crazy values that don't work, VLC media I cannot change either. I'm supposed to be able to use v4l2ucp to change settings, but I don't get the screen that the preview for the program (in Ubuntu Software) showed.

Ubuntu Servers :: Changing Screen Resolution On TV Via HDMI

May 8, 2010

I've just finished installing Ubuntu Server 10.4 onto my ASRock ION330. I don't have a spare monitor lying around, so I've plugged my TV into my machince via HDMI. This works, but the text is tiny. There are too many rows and columns of characters (or equivalently, the font is too small). When I try changing the TV resolution to a smaller size, it just cuts out the rest of the text. So from the command line, how do I make the text bigger?

Ubuntu :: Changing Virtual Console Screen Resolution

Feb 1, 2011

I am using Ubuntu 10.10 on a Dell Optiplex GX270, with the Intel video chip. I have a problem with my virtual consoles/terminals (<ctrl-alt>F1-F6). The default screen resolution was set to 1600x1200 at installation, which results in a nearly microscopic, unreadable font. I posted the problem on this thread on ubuntuforums.org, where they suggested adding GRUB_GFXMODE=640x480 and GRUB_GFXPAYLOAD_LINUX=640x480 to /etc/default/grub and /etc/grub.d/00_header. Still no joy--the console screen resolution still was 1600x1200.

I have noticed that the screen resolution changes three times during boot; it starts at standard VGA, 640x480, then switches to 1600x1200, then finally to 1024x768, which is my preferred resolution in X. But, if I switch to a virtual console, the resolution shoots up to 1600x1200 again. There are times when I like to use virtual terminals, and I would like to avoid eyestrain.

CentOS 5 :: Changing The Resolution In My Computer?

Apr 4, 2010

I am having trouble changing the resolution in my Computer,I am new to Linux and somehow, Lucky, I got this program to install, I installed it on a Dell PowerEdge 1850 with a Radeon 7000 Video card,I had another one set-Up before which gave me a resolution of 1400 x xxxxx? Was great, this one only offers 800 x 600 and some other very low resolutions, The programing allows me to change it and demands I log out, Restart x and log in again, took me a day to figure out what was "x" and how to restart it, but no response. Still the same.

In reading the Forums I see this command allot "/sbin/lspci -m" But, too bad, nobody tells exactly where to type that series of digits to get any response,

Fedora :: Changing What Applications Open Filetypes

Oct 30, 2010

I was tackling this question before using specifics and got nowhere, so now I am going to general. I have a certain application on my machine and many files which can only open using that application. When I open those files, they do not use that application, but use the Archive Manager instead. When I go to "Open With" --> "Other" this application is not in the "other" list. I want to emphasize that because so far everyone assumes too quickly that I didn't try that. This application was installed using the Software Manager, the files that came with fedora. The application is on my machine, this is a fact. I am able to go find the application and open it up manually. Why wouldn't Fedora know that this app is on my machine?

Fedora :: Changing Associated Applications To File Types?

Apr 17, 2009

What file where holds the information for file opening application preferences?

I have Fedora Core 10 (2.6.27.5) with openoffice 3.0 installed.All of the OpenOffice programs show in Applications>Office drop down window and work fine.

Problem is this: If I double click on a calc spreadsheet file (.ods) then the archive manager wants to open it, and I have to right click and manually select scalc as the program to use. If I double click on an odt text file (.odt), okular opens it. I have to right click and select swriter.

If -- BTW -- I click on an excel (.xls) file, calc will start and open the file.

I would like to change these file application preferences, but can't find where to do it or what file to edit to break the current preferences.

Ubuntu Multimedia :: Changing Screen Resolution To Maximum Settings?

Jan 26, 2010

Just got an HP dv6-2150 laptop. Dual boot with Windows 7 and 9.04 (9.10 will not work but that's a different story). The screen resolution is too low and is set at the highest option available (1024x768 which is a 4:3 aspect ratio). The HP uses the new Intel i3-330m chipset with on-board Intel HD graphics. The system is capable of 1366x768 resolution (16:9) - so how do I get it there? xorg.conf looks real generic - nothing specific to Intel.
