Cursor temporarily freezing

Software darktable
1

I recently installed Darktable 4.2.0 on my Framework laptop with Linux Pop! OS. As I’m editing photos I’m noticing the cursor freezing up for a second and then breaking loose. I don’t see this happening outside of Darktable. Could this be a memory issue even though I have 32GB of memory and 4GB of swap space?

My specs are:
12th generation i5-1240P (Up to 4.4 GHz, 4+8 cores)
Crucial RAM 32GB Kit (2x16GB) DDR4 3200MHz
Logitech M185 Wireless Mouse, 2.4GHz with USB Mini Receiver

Any hints greatly appreciated.

Hi @thusband,

Three questions in order to try to get a bit closer to a solution:

  1. Do you have any special graphics card or graphics processor in the machine?
  2. Graphics drivers?
  3. Start darktable from a terminal. Immediately after a mouse freeze, close darktable.
    Any error messages in the terminal window?

Have fun!

  1. Looks like I have:
    VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
    Subsystem: Device f111:0002
    Kernel driver in use: i915
    Kernel modules: i915
  2. Looks my driver is:
    display
    description: VGA compatible controller
    product: Alder Lake-P Integrated Graphics Controller
    vendor: Intel Corporation
    physical id: 2
    bus info: pci@0000:00:02.0
    logical name: /dev/fb0
    version: 0c
    width: 64 bits
    clock: 33MHz
    capabilities: pciexpress msi pm vga_controller bus_master cap_list rom fb
    configuration: depth=32 driver=i915 latency=0 mode=2256x1504 resolution=2
  3. I’m not sure how to start Darktable from the terminal but I’ll continue to search. I installed Darktable as a flatpak if that makes a difference.

Many thanks for the help.

I haven’t figured out how to start Darktable from the terminal and check the log after it freezes.

Are there error logs somewhere that I could check?

Could a reinstall help perhaps? Maybe if I used apt get and not flatpak?

I’m very fuzzy about linux, but I thought you could just type darktable into the terminal and would go… hopefully someone will correct me!

Yes, just launch a Terminal app then type darktable. But if it’s a Flaptak, it’s possible that this doesn’t work and need full path. I don’t use Flatpak and I would recommend to not use it. And maybe, using a debian package (with apt so to install it) would improve speed. It could be good to test. darktable team do not recommend flatpak packages and so do not support them.

To install last darktable release with apt, it’s good to add OBS repository (see install page on darktable.org (and you could find if need thread about that on this forum).

Thanks, launching Darktable in terminal doesn’t seem to work with a flatpak. I think I’m going to uninstall and reinstall with apt. There are some other things that flatpak does like putting files in different places that confuses me.

I’ll look into OBS too. I haven’t heard of it but it sounds like a good idea.

Thanks again.

OK here’s another related question. I’ve opened up OBS so I guess I install the xUbuntu 22.04 version of Darktable?
edit: I’m on Pop! OS.
update: Looks like xUbuntu worked fine (it should have) and, so far I haven’t seen any cursor freezing.

Thanks all!

flatpak run org.darktable. Darktable

If you’re using Wayland, you should go back to X11.

I decided to uninstall the flatpak version and install the apt version. We’ll see how that goes.
