[Locked] Unity in 14.04 has UI scaling that can cause Cairo-dock to always load off screen and be unusable

Messages : 6 		The closest related thread had to do with Fedora 20 when they did UI scaling (http://www.glx-dock.org/bg_topic.php?t=7396).
The closest wiki post is about using Unity and Cairo-dock together (http://www.glx-dock.org/ww_page.php?p=Cairo-Dock%20and%20Unity&lang=en) but it does not handle this case.

Cairo-dock 3.3.2, Ubuntu 14.04, OpenGL on, Compiz, and Unity are in use.

If I leave my scaling at 1, Cairo-dock seems to work. But I need to use a scaling of 2 to make things usable on this high res display.
The steps to do that are to open up System Settings->Displays. Then change 'Scale for menu and title bars' from 1 to 2 and Apply.

This causes Cairo-dock to be scaled off of the bottom of the desktop. If you launch Cairo-dock with this setting already enabled, it appears that nothing happens. But Cairo-dock is indeed running, just invisibly off screen.

Obviously this is very frustrating and most people wouldn't be able to track down the reason for it 'just not working'.

I'd love to see a fix for this since I won't be able to use Cairo-dock on this machine until there is a fix since the scaling is critical for me.

Messages : 12573 		Hello and thank you for this bug report! (and sorry for the delay!)

I was able to reproduce this bug with this command:
gsettings set org.gnome.desktop.interface scaling-factor 2
and to revert back
gsettings set org.gnome.desktop.interface scaling-factor 0


But the X11 server doesn't notify the dock that the resolution (or something else) has changed because the resolution has not changed. It seems that just the DPI of the fonts has changed but it should not be a problem for the dock...
If I try this command when using Compiz, some Compiz effects are broken... (switching between windows/workspaces). Maybe it only works when using an high res display.
I don't think this bug is due to the dock but we will try to recheck again to see what's wrong!

Thank you very much for the reply. The issues occurs on my Chromebook Pixel with a 2560 x 1700 resolution, so the scaling is really important.

My desktop still works fine, but I keep that at a scaling factory of 1 since it is currently only 1680 x 1050.

Thank you for looking into this!

Messages : 12573 		Is it maybe possible to launch the dock with debug informations and report here all new messages you'll have when switching to a bigger scaling factor?
cairo-dock -l debug


And is it also possible to get all new X events that you'll have during this change?
xev -root

I have nearly the identical issue. I am using a MacBook Pro with a screen resolution of 2560x1600 pixels. CairoDock works perfectly as long as I set the scaling factor to 1:

gsettings set org.gnome.desktop.interface scaling-factor 1


However, when I set it back to the default (2), the toolbars are always off the screen:

gsettings set org.gnome.desktop.interface scaling-factor 2


Here are the messages I get when using "cairo-dock -l debug.":

I've installed Ubuntu 14.10 on a Samsung Ativ laptop w/3200x1800 resolution and have the same issue. Cairo dock works fine until I change the "scale for menu and title bars" to a larger value than 1. Then, any dock set to display on the bottom is now off the screen. If I choose to put it on the left it will display but the bottom portion of it is cut off. Hoping a fix can be made soon, otherwise LOVE cairo dock!

Messages : 6 		I'm seeing this on a new Dell 5510 with Ubuntu Gnome. Dock is not visible with scaling factor of 2. Sometimes if I set the dock to appear at the top, it will be visible, but the mouse position seems to be off by about 50% of the screen size. I'm surprised that there don't appear to be more people running into this issue. I've searched all around and can't seem to find much discussion or any suggested solutions to work with scaling.

AthanasiusOfAlex provided the requested logs, is anything more needed to have this looked at?

I really like this dock and want to continue using it, but I can't really run in scaling of 1 on a 4k laptop display.

Is there any news about this problem? i bought a new GPU so i can use the whole Resolution of my 4k TV and now im not able to use cairo Dock anymore
