[Solved] XFCE 4.8 Ghost panel on Second Monitor

I've found that when maximizing a window on my second monitor, there is a 28 pixel "gap" where my panel would be on that screen [If I used a panel on that one] upon maximizing a window. If I set my panel to autohide, this goes away, but I find auto-hiding panels rather annoying, and am wondering if there's any way to fix/workaround this. If it helps, I'm using the command "xrandr --output LVDS1 --right-of HDMI1" to extend my desktop onto the second monitor.
Here's a screenshot of what happens http://img691.imageshack.us/img691/3470 … 103502.png
Edit: Latest version of xfce4-panel fixes the issue.

Yeah, seems to be a limitation of the Nvidia GUI, but it seems that it's possible [and necessary] to configure it with Xorg's configuration files if you want more freedom to position your monitors.
Since some extra configuration is needed with the Nvidia driver, xrandr alone might not be ideal in your situation. [I mentioned it before since I never needed to mess with my Xorg configuration, and an .xprofile script based around xrandr works better with my Intel-based laptop. ]
Xorg's config files seem like a better choice for you, and if you need to change monitor layouts on the fly, xrandr should still work once you have a good Xorg configuration. If you choose to go this route, you'll probably find this section of the Xorg wiki page very useful: https://wiki.archlinux.org/index.php/Xorg#Nvidia_2
Since you'd need to specify a position for your second monitor to workaround this, you'd need to use a line like this, instead of the "RightOf" one in the example configuration: ' Screen 1 "Screen1" x y ' where x,y is the location of the upper left corner of that display.
[If a configuration file already exists, make sure you create a backup of it first. Worst-case scenario, a bad config file will prevent X from starting, and you could just restore the backup from the command-line.]
I also discovered that offsetting it by the exact height of your panel seems to cause problems on your primary monitor [at least with the latest version of the XFCE panel]. Upon rebooting, windows would not respect my panels, and instead would go underneath them when maximized. Although, by offsetting my second monitor by a little more [1920x280 instead of 1920x284], both monitors allow windows to maximize correctly, so if you run into the same problem, something like that should fix it.

Ghost Panels and Misplaced Tool Sub-Menus?

I have a dual-monitor setup and after upgrading from CC to CC 2014 I noticed that any panels I have on my second monitor create a ghost toolbar where any tool sub-menus I click also show up. The attached picture is pretty self-explanatory, the left half of the image is my secondary monitor. I've noticed it in Photoshop and InDesign so far. It doesn't matter if I use my own Workspace or one of the Pre-Defined Workspaces. Has anyone else seen this? Any ideas how to fix it?
I'm running Windows 7 Pro, 64-bit, everything is up to date.
Thanks,
EP

I have not notice that but that may be because my second screen is full of Photoshop Palette. If I want to see what else is on that display I have to use shift Tab to hide Photoshops Palettes. or Alt-Tab to bring a windows application window to the top When I do I have never seen a ghost Image window for a Photoshop Image windows. I keep my image windows in floating windows in Photoshop Main application window on my other display.

[SOLVED] XFCE - Incorrect windows placement

Hi,
I'm currently having a issue with XFCE's window placement. In the settings panel, under Window Manager Tweaks > Placement, window placement is set to Center for all windows, but this option has no effect. I tried changing it to place windows under the mouse, but it also has no effect on the windows placement. Windows keep opening on the screen corners.
I checked the forums for similar problems, and found some results, but none of the solutions worked for me. Also, those are quite old topics.

[solved] Xfce4, new windows position
Xfce 4.8 xfwm4 window placement settings no longer have any effect.
This is not a big problem, but I'm kind of picky, so if anyone knows a solution to this problem, please share it.

Shouldn't you actually have it on the maximum value?
I believe the way this works is that the size (or ratio, the option is actually called placement_ratio IIRC and is a ratio of window size vs screen size) you specify here is the minimum to trigger "smart placement." If the window isn't (at least) of that size, then the default (i.e. center or under mouse pointer, as defined below) will be used. So if you want every window to use the default placement, you should set the minimum size for smart placement to be as large as possible. (In fact, I believe with a ratio set to 100 (i.e. slider to the max) it should always use the default placement, regardless of window size, which is want you're after if I'm not wrong.)
If even with the slider to the max you get new windows placed using smart placement, then it sounds like a bug I'd say.
(Also, just as FYI and though you might simply want all windows to be centered, I wasn't happy with xfwm's smart placement myself, you can see this topic for a (IMO) better alternative.)

[SOLVED] Xfce 4.8 - dual monitor

Hi,

You can set "span monitors" in the panel preferences, and you can lock the panel also I can drag it to another monitor when in it's preferences (it has a red dotted line around it then) works pretty much perfect

Inspector leaves grey "ghost" panel IN ALL TABS after escape/exit

when I use inspector (Q) it often leaves grey ghost panel covering about 3 inches of the bottom of my browser window), where the black html panel was - and it is in EVERY OPEN TAB, and if I try to use it again, it will then open a html panel above the grey "ghost" panel, and sometimes even leave that grey too - I havn't found a way to get rid of it, except for restarting Firefox.
- and "link" labels are above it i.e. it's below the regular bottom of a firefox window

I managed to get it working again but i can't get the resolution higher then 640x480, It should be 1920x1080
edit:
I had to unplug my monitor and reboot.Then i pluged it back in and used gksu/kdesu nvidia-settings and got a resolution of 640x480.After that i just had to reboot again and everything was back to normal.
Also ,the files that were missing from my /home/user/ where easily replaced from the /etc/skel directory and any others that were missing like my .rtorrent.rc just had to be re-downloaded and configured again.

[SOLVED] Extended monitor on a second monitor with Gnome

I was just trying gnome. I have a second monitor (connected to the VGA port). When I configure it as a second monitor extending my desktop, the windows freeze or move erratically and there is no possibility to click / write into them any longer. The same phenomenon appears if I configure the dual screen in gnome (via the settings menu) or if I use the command line xrandr ( xrandr --output LVDS1 --primary --mode 1280x800 --pos 0x0 --output VGA1 --pos -1284x-251 --mode 1280x1024 ). Exactly the same problem appears with Ubuntu 11.04 (tested from the live CD).
The strange fact is that the good old icewm works perfectly fine.
I am not sure this is relevant but here is the output of lspci relative to my graphic card:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
Edited: I mark this thread as solved since the answer of eldragon is convincing (but of course Gnome3 is still not working in my configuration)
Last edited by olive (2011-08-02 20:08:48)

well, your graphics card doesnt support textures bigger than 2048x2048. gnome3 is a composited desktop.
try setting one screen on top of the other one instead.

[SOLVED] Pointer on second monitor distorted after XOrg 1.9 upgrade

I updated to XOrg1.9 and my mouse pointer becomes distorted into a garbled rectangle of noise whenever I move to the second monitor. It's fine on the first. Using Catalyst drivers.
I can still use it, but its a giant garbled blob... anyone else experiencing this?
It looks fine on the first monitor.
EDIT: I replace my ATI card with an Nvidia one and used the nvidia-beta drivers. Mouse pointer looks fabulous on second monitor now. Only cost me $400 to fix my goddamn mouse pointer!

[Solved] no signal w/ second monitor and dual screen using nouveau, i3

Hi!
I just brought my old screen to my room and try to make it work. It works when the other one is not connected, so no hardware problems. The result is that I can go to the right and do stuff and move the window to my working screen, but the monitor stays black and says "no signal". I tried a long time with nouveau but without success. I was not able to make the graphic card work with the propretary driver from the website and I don't want to downgrade the xorg-server to 1.12 to install nvidia-96xx...

Hi!
Thanks for pointing out the repo..I did yaourt -Ss nvidia from the beginning and I didn't pay attention to the nvidia package. Sometimes archlinux is more user-friendly than one expects...
So now my second monitor works. :-)
Moral of the story:
If you want to use the NVIDIA driver, read
https://wiki.archlinux.org/index.php/Nvidia
And if it doesn't work, read
https://wiki.archlinux.org/index.php/Nvidia
again, because maybe you missed something...

ITunes 8 behaves badly on second monitor

Strange problem that I have noticed on my MacPro 2.66. I have two 22" LCDs running on my MacPro with 4GB of RAM and 10.5.5. If I try move the iTunes window on right LCD by grabbing the header bar and dragging the screen will freeze for about 30 seconds. The window will eventually move but the screen will not redraw. If I move the iTunes window to the other LCD it works fine. This only affects iTunes not any other panels on the right LCD. Quitting iTunes and restarting doesn't solve the problem. I did rebuild permissions after I upgraded to 10.5.5.
Can I just restore iTunes 7 from my Time Machine back-up?

Phantom second monitor

Okay, everything was fine til I thought zapping the PRAM might be a good idea yesterday. Not. Finder icons were intermittently not showing up. (hmmmm... now I wonder if the problem might actually have preceded my "fix.")
I'm running 10.3.9 on an upgraded Ethernet dual with a partitioned HD. Zapping the PRAM made the system forget which partition it was supposed to use, so it started up in my stripped down emergency partition, which contained only a system folder. With that as my startup drive, I couldn't even access pref panes to assign the other partition as my startup. I managed finally to solve that headache finding the Startup Disk in the other drive, succeeding in rebooting in that one. Then I CarbonCopy cloned a set of what I thought the small system partition was missing (user, library, pref panes, etc) into the stripped down drive. I then ran Disk Utility and Permissions repair on both partitions. Took about two hours, but got the system acting sane again. All good, BUT...
Now my system believes it is set up with a second monitor, my real monitor set at 1024x768 and a "phantom monitor" at 800 x 600 -- so of course, now I keep losing my curser of the edge of my real monitor into the void of the non-existent one. My guess is that it's reading monitor info off each of the two partitions.
Any suggestions on how I can get the phantom display to go away? No easy "disable second display" button seems to exist...
Oh what tangled webs we weave when first we practice to ... get clever ...

Hi! As you have learned if you want a second smaller partition for emergency use then do a min install and don't install or get rid of the additional languages. But leave everything else. As I recall it takes 6-10 gigs for a basic install. To solve your mouse problem go into the system prefs and open the monitors control panel and see if it shows you both monitors. Click on the title bar in one of them and drag them apart so they aren't touching or drag so they are only corner to corner. Wherever they touch is where the mouse can pass from one to the other.

How to set up a samsung 2433LW monitor as a second monitor?

I have a HP Pavilion Elite HPE running on Windows 7 64bit. I have one monitor attached, a HP 2311x connected using one of the two available DVI ports. When I connect a second monitor, a Samsung 2433LW using the second DVI port, the second monitor is not recognised and has a black no input screen and the original HP monitor loses all shortcut icons and only the desktop background is visible.
Please advise how I can get my second monitor to work.
Thanks.

Does the Samsung 2433LW monitor work by itself on the computer???
It sounds like the Samsung is taking over as the primary display and the HP is becoming the secondary display. Try swapping the DVI cables in the back of the computer and see if that helps. Here is a photo of the back of the original display card in your HP Pavilion Elite HPE-540me Desktop Computer;

Can I connect my HP laptop to the desktop machine in such a way as the laptop does nothing except provide a screen for the Lenovo? (If you've ever got serious about flight simulator you'll know how much you need two or even three screens!! )

Hi,
No you can't you can use other monitor as second monitor for your laptop BUT you can't use laptop monitor as second monitor for other machine.

How to connect a second monitor/TV to HP ENVY Beats All-In-One

Hi, I was wondering if anyone could tell me if it is even possible to connect a second monitor to the HP ENVY Beats All-In-One Desktop PC, because I'm trying to connect my TV as the second monitor through HDMI and I've tried everything that I could, but have come up empty handed?
This question was solved.
View Solution.

Hi,
What is the model/product of your AIO machine ? I many cases, you can't use HDMI port to connect to a TV because it is HDMI IN port. You need USB - HDMI converter/adapter to connect to a TV (or monitor).
