Ubuntu :: Control Of The Compiz Twinview Maximize Function

Jun 28, 2010

Im running a dual monitor setup in gnome, with the closed nvidia drivers in twinview mode. most of the times i want to be able to maximize windows to a single monitor (this is the default behavior in 10.04 lucid i believe), but sometimes i want to span a window on both screens. compiz doesn't allow windows to resized past screenborders, and gdevilspie wasn't able to get past this.

After a lot of googling and toying around i came up with the following sollution, i'm posting it here so other people can enjoy it as well (and i'll be able to find it again after my next install).

I made a script to switch between the streched mode and the doublescreen mode to use it, you'll have to stop the autodetection of the outputs in compiz. this option is found in compiz config settings manager under general settings > display settings or though the gconf-editor in /apps/compiz/general/screen0/options/detect_outputs

This script switches between the two modes, but you need to edit the resolutions of your monitors! (i have a double 1280x1024 setup)


My way of using this:
1. use the script to switch to the span mode
2. start photo/video edit software
3. work
4. close the software
5. use the script to switch back

Ubuntu Multimedia :: Nvidia Twinview Window Maximize Behavior?

Aug 22, 2010

I have 2 nvidia graphics cards and 3 monitors. One graphicss card is an nvidia 460 and the second one is an nvidia 8400 GS. I'm on Ubuntu lucid 64 bit gnome desktop. I use the nvidia drivers . 2 monitors are connected to the 460 card setup as twinview the last monitor is connected to the 8400 GS set as a separate xscreen.

When I now maximize a window on the 2 monitors which are set as twin view it expands this window gets stretched over both screens. I would like to know how I can set it so that an maximized window get only expands on the current screen in twinview so that I can still move windows from 1 screen to another.

Ubuntu :: Compiz With Two Monitors Without TwinView?

Feb 4, 2011

Here is my question:

I recently installed Ubuntu 10.10 (32bit) on an HP compaq nc6400 laptop (internal display is 1280x800, graphics card is an Intel Mobile 945GM/GMS, 943/940GML Express) which I am using in three situations: In my office: external monitor (1280x1024), laptop in docking station with lid closed At home/on travel: as it is, without any external monitor When giving lectures: with projector (1024x786), lid open, same output on projector and internal display As you see, I either want one output device only or both showing the same output. Additionally, I want to run compiz. My problem is that, whenever I (1) connect an external display or (2) when I press the Fn+F4 key to change displays or (3) sometimes even when I open/close the laptop's lid, the system at some point switches to TwinView which seems not to work with compiz on my system. The effect is that compiz is deactivated. When I want to have it back, I have to open the appearance settings and change to extra visual effects again. Unfortunately, that reverts compiz to default settings and I have to adjust my compiz settings again. note that compiz works properly in all three situations I listed above. The problem is "only" that, at some point, it switches to TwinView.

Is there a way to tell X or compiz NEVER TO CHANGE TO TWINVIEW?

Ubuntu :: Compiz Settings For Maximize / Tiling

Mar 9, 2011

I have been missing this feature from windows, and had thought I would just have to do without, but today, people have alluded that it is possible to do with compiz. I am referring to the ability to take a window, drag it to the edge of the screen and it to then fill up that side of the screen.. or if drug to the top, maximize itself. I have looked and messed with settings, and have been able to do something to the effect of dragging my mouse to the edge of the screen will kind of tile windows, but it does it to all my windows or all of a certain type and whatnot.

And I want to do it to a specific window, and then another - for the side by side viewing. it also does not vertically maximize it, only taking a portion of the screen from top to bottom. I have been able to do it this way by having only 2 windows open and using a keyboard to do so, but i would like to be able to use only my mouse. Is there a way to drag one window the the edge of the screen and have it maximize to that half-side of the screen AND/OR drag to the top and have it maximize to fullscreen?

Ubuntu :: Compiz Window Rules - Maximize Size Below Panel?

Jul 6, 2011

I can't stand looking at the ugly, off-center, non-themed maximize/minimize/close buttons in the maximized global menu. Is it possible to set a window to maximize *below* the top panel? Or at least to have its set fixed size be its fixed size when not maximized?

Using Compiz window rules I've been able to set a fixed size in some applications (Opera, for example), but whenever I open them, the window automatically opens as maximized. When I un-maximize, it reverts to whatever size it wants, and having to resize my windows all the time is a pain.

Software :: Compiz No Minimize, Maximize, Or Close Menu?

Dec 17, 2008

I am using compiz in Kubuntu and I have run across an interesting problem. Occasionally when I reboot and login kubuntu will load but there is no window manager (ie no minimize, maximize, or close) and compiz doesn't actually load (no effects work). Like I said this only happens occasionally. I can fix the problem by using the following command:compiz --replaceOnce I type this command compiz loads and the window manager finishes loading as well. Other times when I reboot Kubuntu will load just find as well as compiz automatically with no problems. The problem is really intermittent. Any ideas on how to fix the problem?I installed the program through the adept-manager and I enabled it through the kubuntu menu->system->desktop effectsI didn't modify any file to make it load automatically it just did it by itself. I also do not have any nvidia card installed and once compiz is loaded it runs flawlessly.

Fedora :: Bash - Binding A Function To Control-something Key Combo - F11

Aug 20, 2009

I want to set a key binding in bash for "history-search-backward" readline command to a combination of Control+some other key (I'm using 2 as an example), but I'm unable to do so. in fact, I'm unable to alter or add bindings to Control+key combinations.

After several tries my ~/.inputrc now looks like this

But it doesn't work and bind -p | grep "-2" gives nothing. If I try something without the control key:

I can search in the history by prssing the sequence C + - + 2.

bind -p gives control in C form, for example:

I've tried different formats in my inputrc:

But nothing works.

works if I press Escape followed by 2.

Fedora 11:
Bash version 4.0.23(1)
GNU Readline 5.2 (according to the man page)

Ubuntu :: Compiz Rendering VLC Fullscreen Video - Cannot Control Playback?

Feb 28, 2011

I have Compiz Config Settings Manager installed on my Ubuntu 10.04 machine. All the effects are working properly and everything is running fine. However when i play video with VLC Media Player, i would only get audio and no video. After looking this up i changed the output to X11 vidoe Output. I started getting video and audio. But when i switch to fullscreen mode the fullscreen video window is rendered by Compiz and thus has all of those window effects like wobbly, minimize, maximize and stuff are also applied to the full screen video. It also does not have all those controls that vlc normally shows when you wiggle your mouse in full-screen mode. I tried disabling the Video Playback option from the CCSM window, but to no avail.

The same thing also happens for the full screen view of Google Chrome. And the only way to leave full screen is to press F11 again. In this case the tab stacking area which drops down doesn't appear at all, also the exit full screen option which too drops down also does not appear. It seems Compiz is blocking all of those interactive buttons like the floating control panel in VLC and Tab stacking area in Chrome.

Ubuntu :: NVidia Twinview Not Working?

Jun 17, 2010

I have no idea what to do to get Twinview to work. I had found a bit of code to paste into the xorg.conf file but after I pasted it in and restarted my computer, but it wouldn't boot up. Whenever I open up the "Monitors" dialog under System>Preferences, it doesn't even see that the second monitor is there! It doesn't matter if I go to the default tool or if I go to nVidia's tool. On the nVidia tool, under X "Server Display Configuration", there is a button "Configure...", when I press it, it asks "How should this display be configured?". The options "Twinview" and "Disabled" are both unselectable and the only one that I can select is "Separate X Screen". It's almost like my computer doesn't know that I have a second monitor plug.

I am running Ubuntu 10.04.

My xorg.conf:

Section "Device"
Identifier "nVidia Corporation NV34 [GeForce FX 5200]"
Driver "nvidia"
Option "NvAGP" "1"

Ubuntu :: Twinview & Maximizing Not Working Correctly?

Apr 18, 2011

I am having issues maximizing windows/applications on triple monitor setup. I would like to maximize wine, folder explorer, media players, and etc to one screen, instead of across both, which it is currently doing that. Using Separate X [xinerama] + twinview, but I have also tried without xinerama + twinview. When maximizing applications and such, it will only maximizes across both of the monitors in the twinview setup, not the separate X on the left. The separate x has maximizing working to that one screen. I have tried to add xorg tweets, but that's not working, and they are currently in my xorg post below. I had maximizing to one screen working perfectly with dual monitor setup. :S And, I am currently getting an error about " Xlib: extension "RANDR" missing on display ":0.0""

The following Xorgs show the differences, I guess if there is one between maximizing correctly to one screen.

Triple Monitor setup, maximizing across both twinview monitors, not preferred:

# nvidia-settings: version 260.19.06 (buildd@yellow) Mon Oct 4 15:59:51 UTC 2010

Ubuntu :: Configuring My Xorg.conf With Dual Monitor - TwinView

Jul 1, 2009

I have a dual monitor setup (Twinview), both monitors are connected to my 1xNvidia MSI NX8600GT card...I've been using a 21.6inch HannsG HG216D (herein referred to as HG216D) monitor as my LEFT monitor, and a Dell 1905fp (herein referred to as 1905fp) as my RIGHT monitor.

I recently got rid of the 19inch 1905fp Dell monitor and moved my HG216D to the RIGHT and now I have a new 23inch DELL S2309W (herein referred to as S2309W) on the left. The new S2309W is connected to my computer via DVI cable and is configured Perfectly at it's native 1920x1080 resolution.

However I can't for the life of me get my HG216D back to it's native 1680x1050. The HG216D is connected via VGA cable that is also routed thru a KVM, I realize this means that this monitor can't/won't be auto-configured. However I should be allowed to set it manually right?...


Won't let me select 1680x1050 for the HG216D resolution, it will only let me select 1440x900 MAX, there is no option for 1680x1050, (See attached: screenshot)

I've tried to manually edit my /etc/X11/xorg.conf, but after hours on end messing with it, I give UP...

Here is my current xorg.conf:


I am just not sure what I need to change and how to get the second xorg.conf to play nice via a VGA connection?

Programming :: Passing Data From Interrupt Handler Function To Tasklet Function?

May 18, 2010

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

OpenSUSE Hardware :: Twinview Second Monitor No Wallpaper?

Feb 24, 2011

I'm running the latest versions of openSUSE and KDE with latest updates installed. I have an nVidia GTS 250 video card with two monitors hooked up. Initially SUSE recognized my second monitor just fine. However, after installing nVidia's own driver (to quiet the loud noise of the card's fan on high) following these instructions, my monitor is only usable after I go into the nVidia X Server Settings (from terminal, as root: "nvidia-settings") and configure it to TwinView.

All is well and good (I can move windows over to monitor 2), except that monitor 2 has no wallpaper (I'm new to KDE, does this mean that monitor has no desktop activity?) and the X Server configuration is not persistent. When I reboot I have to change the X Server settings back to get monitor 2 recognized again.

I tried looking for the X Server configuration file (xorg.conf, right?), in order to replace it with the edited version, but could not find it.

CentOS 5 :: Can't Get TwinView/DualHead Display To Work

Jun 4, 2010

I have 32-bit Windows XP and Centos 5.5 x86_64 on my dual-boot PC, equipped with two generic LCD monitors, Dell (primary) and HP (secondary). I have been running dual screen displays without any problem when running Windows, however no luck getting them to work when I boot up with my newly installed Centos 5.5

In both Gnome and KDE both monitors light up, but secondary monitor (HP) is just a clone of the primary. I have tried setting "Dual Head" in the Display adminitrator but the resulting xorg.conf causes a "Entity is already in use" error and crashes. I have also tried just adding Option "TwinView" "on" but it does nothing. (Are "Dual Head" and "Twin View" exactly the same concept?)

What I am doing wrong? I checked the FAQ and did not find any similar problems being discussed.

Below is my getinfo.sh driver info

== BEGIN uname -rmi ==
2.6.18-194.3.1.el5.centos.plusxen x86_64 x86_64

Ubuntu :: Twinview - Previously Maximized Windows Open To Wrong Display?

Dec 15, 2010

I am currently running ubuntu 10.10

I have a panasonic 50" and a samsung 23" both of which are 1080p displays. I have twinview setup so that the samsung is my main and the panasonic plasma is my secondary. For some reason every time I open a windows of lets say mozilla and it was maximized prior to closing before, it will "jump" (briefly display on the samsung monitor for a split second and then automatically move to the plasma) from my main display to the secondary panasonic plasma. If mozilla was minimized before closing prior and I reopen it will open to the samsung in the state it was in on the prior close (aka minimized), which is fine. Only when it was maximized prior does it "jump" to my secondary display.

How can I correct this issue? I would like to have programs open (and stay) in the display they were launched in whether it is the plasma or the samsung.

-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).

Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?
