Hi all!
I am running ExpertSDR2 on Linux and I am having performance issues. I was wondering if anyone has any thoughts on what might be the cause. The screen updates slowly and it gets worse when I try to move the mouse over either the waterfall or panadapter. Sometimes I can find a spot on the top button bar area or off of the program screen and the waterfall will start responding normally. I have tried the current version of the software and the 1.2 version - each respond the same way. I have 4 cores and the software is using 113% of cpu as reported by top. (400% would be all 4 cores in use). Not running out of memory or cpu... thoughts?

HW/SW details:
Machine: Mac Mini
os: Ubuntu 18.04.3 LTS 64-bit
cpu: Intel Core i5-2415M @ 2.3GHZ x4
graphics: intel sandybridge mobile
memory: 16gig
disk: ssd

I have the same issue.

Using Debian 10 Buster:
Intel® Core™ i7-8550U CPU @ 1.80GHz × 8
Gnome: 3.30.2
Intel® UHD Graphics 620 (Kabylake GT2)
200GB disk
Memory: 16GB
Then the sound is also garbled.

Running 1.3.1 Update 4 of SunSDR DX2

I do have the following errors on startup - as seen when I start from shell:

Hi,
I am also running a SunSDR2 Plus with a Linux-PC. I have the same errors on startup as show above and some more.
But my system is running without the listed problems.

my system is:
CPU: Core i5 Clarkdale i5-660 @ 3.3GHz x 2
Memory: 8 GB
Linux: Arch-Linux (rolling release)
Desk: Cinnamon

The only problem I am dealing with from time to time are underruns in the soundsystem for the VACs.
This then generates ugly pops in the transmitted signal.

Best 73, Dieter DK6OV

I have the same errors regarding Jack and libdb-5.3.so

Can both of you please send me the results from:
sudo apt list --installed

Then i can compare and see if it's a package missing etc.

Awesome to see I'm not the only Arch Linux fan here but you might want to try putting in a hardware accelerated GPU to improve the display update rate. I have a similar set up on my Linux rig that I use my SunSDR2 with but have no issues with display updating. I have an nVidia GTX 970 in it though and SSD. Other than that the specs are just about the same.
Current set up: SunSDR2 DX, HiFi audio, Alpha Delta DX-CC up 20 feet.

I don't want to throw hardware at the problem. The PC is a mac mini (which I cant add a gpu) and I run an identical mac mini with windows 10 which has no problems running expertsdr2 and 2 other SDR packages at the same time (Elad-duo and Flex-5000a). So there must be a set of tunables or some problem that needs to be diagnosed.

I'm not completely sure that the Linux kernel fully supports the Intel HD GPU for acceleration and that might be the core of the issue.
