xorg.conf

I have a really weird problem when setting my display collor depth to 30 bit, first I create a xorg.conf file using nvidia X server settings, save to X configuration file, I restart the computer and everything works including the mouse in the new server settings, after that I edit the xorg.conf file and change DefaultDepth and Depth to 30 and restart (my monitor supports 10 bit per collor), then the mouse left and right button stops working in gnome shell.

I am using an nvidia 1060 6GB on Ubuntu gnome 17.04 amd64 and nvidia drivers 384.69 provided by ubuntu.

Even though xorg.conf specifies the "mouse" driver, the log file shows:
[     3.412] (WW) Hotplugging is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.

[     4.116] (II) config/udev: Adding input device Logitech USB Receiver (/dev/input/event2)
[     4.116] (**) Logitech USB Receiver: Applying InputClass "libinput pointer catchall"
[     4.116] (II) Using input driver 'libinput' for 'Logitech USB Receiver'

so moving from "mouse" driver to "libinput" driver bug category.

I'm going to say that unless you can reproduce this with a free driver, it's unlikely that this will get fixed. I can't even imagine what could trigger this but given that the libinput driver doesn't know about the display at all, it's either a server bug or a bug in the nvidia driver.

I have removed the nvidia driver and tried with nouveau, although I couldn't get pass GDM with 30 bit precision, the mouse buttons worked on GDM unlike the nvidia drivers, so this is a nvidia bug?

Note that gdm these days runs on Wayland and ignores the xorg.conf. It then starts the server and if it drops you back to gdm this means the the xorg.conf with nouveau most likely didn't work. I'm still blaming the nvidia driver for this bug though :)

We ran into the same problem and determined that it's a GNOME bug, although I don't recall what steps were taken to investigate it.

It also crashes trying to start xterm at depth 30 due to some sort of icon thumbnail bug, for what it's worth.

Doesn't xf86-video-intel support depth 30? Maybe someone could try it with that.

I've found a bug report on gnome bugzilla https://bugzilla.gnome.org/show_bug.cgi?id=743620

I can confirm the same issue with amdgpu-pro driver. Keyboard works fine and Krita shows 30-bit images well, but all the GNOME shell is irresponsible to mouse clicks. Apps react on clicks as usual.

Having the same issue on Ubuntu 18.04.02 (5.0.7) with 418 Nvidia drivers. I can't enable 30 bit color depth or HDR on my monitor either. Very same pc can activate it on Windows 10.
