Fedora :: Preventing Apps From Opening On A 2nd Monitor?
Mar 15, 2011
I have a 2 monitor configuration, with the second monitor uses exclusively for mythtv. When I'm not actually watching tv or a muvie or watching visualizations with music playing, I actually use the machine for more productive uses. As the result the second monitor is typically not turned on, might have something to do the the fact it's a crt design, consumes a fair bit of power and does a good job keeping the media room overly warm.
The question is, does Fedora 11 or newer have a means to prevent applications from opening on the second monitor? I've checked the obvious places and nothing jumps out .
btw: According to the nvidia x server settings control panel the second monitor is set up as in twinview mode. This mode was chosen to allow the gpu to do most of the video decoding tasks using vdupau or something as I recall.

I have openSUSE 11.2 KDE with NVIDIA drivers. I have a TV on the left and a monitor on the right. In the Nvidia drivers this has also been setup as stated. The TV is on position 0:0 and the monitor is in position 1920:0. The monitor has been ticked in the drivers as the primary screen.
My problem is that all application open on the secondary screen and not the primary screen (monitor) as I expect. How to the OS/drivers that will ensure that application always open on the monitor situated on the right are welcome.

I just installed Ubuntu 10.10 64bit. I installed VirtualBox ( AMD64 bit version) from here [URL] however whenever I went to run it, it would cause the system to log out (not shut down, just drop out) and return to the login screen. I thought this could be an issue with that version of VirtualBox so I uninstalled and and then installed the version through the Software Centre, however unfortunately it was causing the same problem. I thought this may be a VirtualBox specific issue, however the same thing is now happening since I installed skype (again only when I run Skype).
I understand the description I am giving is very vague, and as such my first question would be : how am I able to produce an error report (of such) that would better suffice in describing the problem? Obviously, if anyone has come across this problem, do they know how to fix it? Sorry, one last thing, and I'm not sure if this matters at all, but I'm running three monitors over two video cards using the Nvidia driver with Xinerema. I only bring this up, because a while back I was running 10.04 with two monitors in Twinview and had no problems.

I recently installed KDE and began using that instead of Unity (less buggy, IMHO) and it was running smoothly until I began configuring my GTK applications for transition in that. I installed the Oxygen-GTK them from gnome-look.org and set that as my default theme for GTK applications under the KDE appearance preferences.
When I log in, however, GTK applications just use the stock Xorg theme until I run "gnome-appearance-properties" in my terminal.I believe that a fix involving .gtkrc would suffice, but I honestly cannot configure it no matter how hard I try.

I have a multi-head system (three monitors). Using KDE 3.6 I was able to specify that new windows were to open on the monitor on which the mouse cursor was located. I don't recall where the setting was configured but I can't find anything like it in 4.3. Is there somewhere I can set this option or is it no longer available?

I'm running CentOS 5.4 on an Atom-based motherboard with a quiet, low-power PSU. As the only fan left is a 40mm fan to cool the Intel 945GC chip, I'd like to run a utility to monitor the 945GC and HD temperatures. Ideally, it should be able to run the 945GC fan faster when it's needed.

Every time I open an app or window in Kubuntu 10.10, they open up on the secondary monitor. I would like them to open up on the main screen because I don't always want to use my second screen. Is there a setting I'm missing?

I use 2 monitors under Ubuntu 9.10, but I have them set up in a unique way. The primary (CRT) faces me on my desk, but the other (widescreen LCD) is turned away from me, because I use it only to watch movies from my couch. My video card is an Nvidia GeForce 9800 GTX+, using the proprietary Nvidia driver package, with Xinerama turned on, so the desktop extends across both displays. Given that setup, is there any way to control which display applications open upon? Several apps have started opening on one display or the other, seemingly at random. Further, some apps start on the primary display, but open their subwindows on the secondary display. It's very annoying, because I can't see the second screen, so I can't drag the windows back to the primary desktop.
I would also like to have VLC Media Player (or any other app) always open on the secondary screen, on purpose. I almost never watch movies sitting at my desk, but rather from the couch. I placed a VLC launcher icon on the secondary screen, but when started it opens on the primary display. (If you're wondering how I can click on anything from my couch, I have a wireless mouse there in addition to the wired mouse at my desk. It's my "remote" since I don't have a TV. Xorg will quite happily support 2 or more mice simultaneously, I discovered.)

just a quick question: I have an external HD with 2 partitions, one ext3 and one FAT32.When I plug in the HD both partitions get automatically mounted, but as I only use I use the FAT32 partition to transfer data from/to Windows machines (which does not happen so often) I would like only the ext3 partition to be mounted automatically.

I'm using the Fedora Eee kernel for Fedora 12 (it's an unofficial kernel for the Eee PC), and want to update my system (I just set it up today). How can I update via command line and prevent an update to the default kernel?

I have a virtualbox installation, and I need fairly high security separation between host and guest traffic. The university network the box hangs off uses statically-allocated ip addresses, allocated to fixed MAC addresses (i.e. it eats any traffic with mismatched ip and MAC addresses).
VBox: 3.0.4
Guest OS: Fedora 11 64bit
Hardware: dual NIC, Intel server
Bridged networking, with separate NICs for host and guest
I'm aiming for high-security separation between host and guest traffic. To do this, I would like to to run all host traffic through one NIC, H, and all guest traffic through the other, G. The host and guest have separate, statically allocated, IP addresses, IPH and IPG. The network forces these to be mapped to specific MAC addresses, MACH (the address of NIC H) and MACG (the address of NIC G). So it's not too hard to write host firewall rules to enforce this policy. The rules just have to state that traffic coming into H must have a destination compatible with IPH, and traffic going out must have IPH as source - and vv for G and IPG. There also don't seem to be any trouble telling the guest to only use NIC G. As a result, turning off NIC G (or equivalently, firewalling it off from host traffic) crashes the network, I have to reboot it to get networking working.
But I can't figure how to tell the host to _only_ use NIC H for anything else except the guest. Even though we don't see any IPH traffic coming into NIC G from outside, I don't seem to be able to stop the host from starting connections on NIC G. Does anyone know any way to do this - to tell the host that it can only use IPH as its IP address unless traffic is coming from a guest process, and that it can only use address MACH and NIC H? I've been reading route and arp manuals all day, but I can't seem to figure anything on this - mainly because arp and route don't know about host/guest processes, and I guess weren't designed with this in mind...

I'm running F13 with KDE 4.4.4 on my desktop PC. A few months ago I had occasion to run Kalarm (invoked via "Kickoff" app launcher). Ever since that time, the Kalarm icon appears in my KDE "system tray" after I login. I power down my PC when I'm finished using it for the day.In an effort to get rid of the Kalarm icon, I changed my KDE "session manager" (System settings -> Advanced -> Session Manager) settings to: "on login: start with an empty session". But the Kalarm icon still appears in my "system tray" after the next reboot/login.I've also tried right-clicking on the Kalarm icon and selecting "quit". The icon still re-appears after the next reboot/login.Why didn't the session manager setting: "on login: start with an empty session" get rid of the Kalarm icon?

I'm having trouble booting after a recent bunch of updates (haven't been able to boot F12 from hard disk for a couple of days). The boot process gets as far as "NetworkManager daemon [OK]", then just stops.

is it possible to block an application from using the network? If yes, how? I read it's possible with iptables and with selinux... Also, what about creating a user who can't connect and run the application with that user?

When I'm logged into my account, I can't shut down the computer if someone else is also logged in unless I supply the root password. However, if I log out, I can shut down from GDM without being challenged, even though another person is logged in, which could cause problems if that person is in the middle of some work. Is there a way to password-protect the gdm shutdown function if people are logged in?

My Fedora box is giving me an SELinux security error:
Code: Summary:
SELinux is preventing the samba daemon from reading users' home directories.
Detailed Description:
SELinux has denied the samba daemon access to users' home directories. Someone
is attempting to access your home directories via your samba daemon. If you only
setup samba to share non-home directories, this probably signals an intrusion
attempt. For more information on SELinux integration with samba, look at the
samba_selinux man page. (man samba_selinux)
Allowing Access: If you want samba to share home directories you need to turn on the
samba_enable_home_dirs boolean: "setsebool -P samba_enable_home_dirs=1"
Fix Command:
setsebool -P samba_enable_home_dirs=1
Additional Information:
Source Context system_u:system_r:smbd_t:s0
Target Context unconfined_u:object_r:user_home_dir_t:s0
Target Objects /home/micah [ dir ]
Source smbd

I went to print something and I get this message: Summary: SELinux is preventing access to files with the default label, default_t.
Detailed Description: SELinux permission checks on files labeled default_t are being denied. These files/directories have the default label on them. This can indicate a labeling problem, especially if the files being referred to are not top level directories. Any files/directories under standard system directories, /usr, /var. /dev, /tmp, ..., should not be labeled with the default label. The default label is for files/directories which do not have a label on a parent directory. So if you create a new directory in / you might legitimately get this label.

I am facing problem with the fresh installation of Fedora 11. (I have moved from Fedora 9). When I try to view videos on ..... or use the Cheese Webcam Booth, I get blurred lines on the screen and I am unable to see any video or pic.
Also I noticed that the when i go to System > Preferences>Display, it shows me UNKOWN MONIOR.
However, if I got to System>Administration>Display and enter the su password, it shows me correct monitor and the graphics driver.
I am not sure if my original is related to the Unknown Monitor.
I also tried to install Nvidia driver but it crashed the xserver and I had remove the driver.
My Monitor is LG 700E and Graphics card is from intel. as I am not able watch any video.

I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again.
When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
I have a Thinkpad E420, Fedora 15

My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.
My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.
Code:
How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.

I just upgrade to F14 from F10 on a dual montor setup. Firefox behaives differently on F14 than on F10.
On F10 it followed the mouse pointer's location and show up on the correct monitor
When maximized at close, it is always displayed on the left monitor. When not maximized at close it will open on the monitor where the mouse pointer is located.
About minimize/maximize Firefoxe before closing and it seems to work in some case, but not for me.
