I'm not sure you would benefit from OpenCL. As someone already pointed
out, you need a somewhat decent GPU to make use of it. Did it work
before the upgrade to 16.04?
Your overall slow performance may also be due to heat problems. Have you
checked the temperature of your CPU and GPU? Older laptops get filled up
with dust. The CPU/GPU reaches higher temperatures and throttles itself.
Windows, btw, is never the solution ;)

I thank you all for your comments.
There's another issue that I thought last night, about changing
operating systems. I produce some publications, photobooks, etc, with
a software that I choose only because it has a Linux version. They
have a windows version, of course, but my books were made in this
filesystem, with these photo locations. If I change to windows,
pathnames would not match and I thing I would loose my work.
This only would prevent me to change OS.
Well, I think I could try to go back to 14.04 and use the packaged
version of dt. Since its an old computer, maybe I should stick with an
old OS version ?

I always used it from PPA. I understand there is some dependency
that only comes with 16.04. To my knowledge - the only benefit to
use Open CL (if this is your goal) is if the GPU is very fast. I
can use Open CL "GeForce GT 525M/PCIe/SSE2" - I believe 2 GB
memory for the GPU but I have no speed benefits because my GPU is
too old (my whole computer is too old actually). For speed - I use
the CPU. My only benefit for the GPU is to have a real monitor
plugged to the laptop.
I got burned before with AMD...
And with that old computer - I am processing still quite a bit of
pictures (thousands actually) - thanks to DT....

Hi,
Is there a way to compile the latest dt for a Ubuntu 14 trusty
tahr, where I can use AMD catalyst driver for an old graphic-card?

For what is worth...
I am using DT on Dell XPS (mid 2011) - this is i7 (gen 2) -
machine 8GB RAM SSD Samsung 512 GB with Ubuntu 16.04.
Compared to
DT on Dell Inspiron (late 2014) - this is i5 (gen 4) - machine
8GB RAM same SSD Samsung 512 GB with Windows 10 64 bit home
edition fully updated.
For now - I am _not_ going back to Windows. And the issue is not
only with DT - everything on windows is much slower. So much so
that nobody at home can stand it most of the time except my
daughter who plays some games on it.
I know I am comparing i5 vs i7 but the windows is 3 years newer
machine (and I have tested it on Linux - live CD and it does
work much better in terms of speed).

Hi Matej,
Yes, I have:
$ glxinfo | grep "OpenGL version"
*OpenGL version string: 3.0 Mesa 17.3.2 - padoka PPA*
But I still cant get Opencl to work.
In fact, I've been thinking if this slowness may be fault of
these alternative drivers.

Have you tried mesa?

Hello dt users,
I don't use Windows for more than 5 years and used to be
very happy with Linux (Ubuntu, in my case). Until Ubuntu
14.04 or 15.10 I was, at least. In that time, I could use
the AMD HD 7730M 2gb GPU of my Dell Inspiron 7520 Core I7
notebook, 8gb RAM.
When dt started to use GTK 3.0, I had to upgrade to Ubuntu
16.04, in order to be able to compile the package.
With Ubuntu 16.04, I lost the graphics card proprietary
driver. No more AmdGPU, no more Opencl, and my computer is
like a snail nowadays... Even with fresh installation of
Ubuntu 16.04.
My options are:
Buy a new Laptop (maybe a Gamer machine with Geforce 1050)
for a lot of cash,
or.....
Say goodbye to Linux and go back to Windows, since AMD
still supports my graphics card (last update
february/2018) and dt now runs on Windows.
My questions are:
1) Is dt for windows stable, right now?
2) What are your opinion about the above scenario?
Thank you in advance!
