Bump…I also have often high cpu usage on gdm process it raises above 20% It seems happens with randomness in time. For example it can raise on using my browser google chrome but when I use “shift+Esc” combination in my browser it shows up browser task manager and there is no processes cost so much cpu only 1 or 2 points in there so there is definitely not an google chrome or “docky” problem. (I have also crashed Docky few minutes ago…).
But in terms of memory leaks I dunno how to look at it it seems to eat about 350Mb’s according to my searches for gdm processes in htop.
And these high cpu usages happens very randomly to me. Weird thing I even want to switch away from gnome or KDE and try something like MATE, but it still like Cinnamon and forked from same gnome code base and I know that Cinnamon its even more lags then Mate or Gnome…The KDE now uses sddm for their window manager cause recent wm that they are using giving flickering problems on nvidia binary drivers. And I am only experience well nice work on Ubuntu with their unity + lightdm it feels much more faster and responsive compared to any gnome-shell or my recent KDE experience.
I think that is why Ubuntu developers starting unity and using lightdm instead of gdm or sddm or something else cause they are work around these X11 bugs that can be also related to when using nvidia binary blob ;(
I am starting to using Sabayon 16 on long term basis and using it for more then 2 month at these moment, unfortunately I won’t like to use Ubuntu until 16.04 next LTS will come out, and SUSE Leap does not looking mature distro for me cause they even not aware of KDE is should use sddm or anything others then what they used up and kills me with these nvidia tearing flickering desktop experience bugs ;( I also using Manjaro but they are too not aware of these terrible thing. I mean I understand that it can be fixed up by myself but wtf I am a bit more like lazy and just want to use nice rolling distro that updates recently and don’t have these pain so I just Install sabayon on my new dedicated hdd and leave other distros installed on 5 or more dedicated hdd’s ;D So its a matter of switching hdd’s to boot something other distro for me (don’t like to mess with grub partitioning or chain load anything).
The problem is that unity libs are bad combines when you for example install gnome near…in ubuntu…I do not try to use unity on other distros. I think its not worse efforts cause I like default desktop expericence.
Anyway I think we should wait until Linux world adopts to new wayland protocol and programs landing some support of it in their code base. And I still have a little hope that nvidia will share some stuff with nouveau project or open source their drvier ;D
Well at least I have no TDR’s here on Linux. I leave windows world about half year ago and it fine, I’d really wont like to install any redaction of windows anymore.
