Take a look at this:
https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=amdgpu-pro-installer

This is how archlinux does the install for amdgpu-pro. In this
case, they use debian. It will show you what you are most likely
missing.

My guess is he is referring to USD. In Canada (with our weak dollar) a
4GB RX 460 is around $180:

Hello,

Would you be able to tell me how you unpacked the rpm files?

I've been unsuccessful with rpm2cpio. I've also tried file-roller. Both
fail.

Thanks

We had an issue with fvwm2 a while ago, it was due to broken scripts shipped 
with it or something like that. See
   http://fvwm.org/documentation/manpages/fvwm.html
and search for "urgency hint". It will tell you how to fix your system.

dt is using a standard X11 feature of setting a hint for the window that the 
window manager can react to. See above how to fix your system.

Interesting.  By which means is this implemented (pointer to source
code is welcome)?  Maybe it's a bug in FVWM then, I could try to
figure this out.  On the other hand, it's the only program I use which
is stealing focus this way.

Which card is this? The couple that I've seen at that price where 460
on sale but with only 2Gb.

Sure, you can't generally use any RC candidate and need to follow the
official releases.

The fact is that the situation is very bad with AMD for darktable. We
are many devs having issues with cards not supported by AMDGPU-PRO and
AMD has had a bad move when deprecating fglrx driver without giving
support for all card in newest AMDGPU-PRO.

This is just a friendly message for those choosing a new config, you
must make sure that the AMD *is* supported by AMDGPU-PRO otherwise no
luck. I've just changed my notebook just for this.

calling only the kernel module part the "driver", whereas the driver does
include both kernel and userspace parts.

I just wanted to point out that it is convenient being able to use an
upstream kernel module, and believe me, I've been using dkms nvidia modules
for almost a decade, with its share of problems (namely can't upgrade
kernels easily)

But yes, if the past is to show, if you don't care about upgrading to newer
kernels, or possibly crappy support for older cards, and cost, then NVIDIA
is a better choice; but I just wanted to point out that if you're buying a
new card, the low end AMD RX-4 series are a _really_ good value.

What window manager are you using? It's supposed to notice you with some 
visual indicator that it is done with whatever it did – on kde the entry in 
the task bar flashes once and gets a colored background then. I never heard of 
environments giving focus to darktable.

As a fellow focus-follows-mouse user, I agree -- simply moving your
mouse out of a widget should not apply changes.  Committing an edit
isn't something that should be done by an inadvertent action, like
moving your mouse outside of the window/widget; it should take an
explicit action (a save key/menu item, confirmation, or the like).

You're kidding right, a few libraries from the proprietary AMDGPU-PRO
driver, why are you saying this is not the proprietary driver

Not tested, but the dkms package from Debian is *always* working with
the current kernel on any branch (stable, testing, unstable). Current
kernel is 4.9. When 4.10 will be out it will be working. I've not had
bad experience since many years using latest stable kernel.

And again it is working for you because you are lucky to have a
supported AMD card. But I've already said that 3 times in this
thread...

The original subject was about being able to *not* use the proprietary
drivers for AMD, but just a few libraries extracted from the package.

It worked like a charm for me on the latest Ubuntu: open source drivers on
the latest kernel 4.11 RC!

Nvidia doesn't even support this kernel right now afaik.

My $150 AMD RX 460 4GB seems to be by far the best value when you're
building a machine for doing image work in opencl, so as long as the new
cards are well supported, I can't see myself buying the doubly expensive
nvidia cards (the dark table benchmarks for the 1060 show it only being
marginally faster for double the price)

And this is quite surprising, let me tell you. I am quite old and geeky 
(is there a single word for that?) so I am one of the 5 in the world 
that uses focus-follow-mouse [FFM] in my normal desktop (and I had to 
develop a Gnome extension to switch to click-to-focus for the buggy 
programs that needs it, like all windows programs running under 
wine...), so I do not object to most of the thing underlined in this 
thread.


But in my opinion one thing is removing text input when mouse go away 
(which I find natural, given the above) and another one commit changes. 
FFM is useful because while I'm doing thing in a window, I can rapidly 
move the mouse to, say, IRC to answer and go back. I expect that from 
the mouse (and focus) exit to the re-enter nothing happens. It is a bit 
like if I am typing "rm -f *.log" in a xterm, move to another one after 
typing the "*", and having the command executed...


On a general way, the state of the undo in DT is, I think, getting 
better and better. I would like to see undo or (less optimal) 
confirmation on all destructive operations, and I think it will get 
there with time. It would be nice to simply have a "timemachine" folder 
where the last ten version of the xmp files where stored (they are small 
and cheap to store), and I had even tried to check some filesystem doing 
that (like the old yore VAX-VMS one...), to no avail. Maybe it is 
possible to do this with a LUA script?

Re: [darktable-user] Does OpenCL require the AMDGPU-PRO driver? Yes, but does not require installation, just some libs

But that's not what we are discussing. Look at the subject, this is
about OpenCL and the situation is clear, for OpenCL you need the
proprietary driver for AMD and NVIDIA.
 
And as stated here many times by multiple users AMD has big issues with
many configurations whereas NVIDIA support for more GPU and even some
quite old.

That's the important point to keep in mind for people about to build a
new configuration.

I know. But CUDA also needs the proprietary drivers, which was my point.
If you don't want to use proprietary drivers, NVidia has no advantages, afaik.

The reason why we take away keyboard focus when the mouse leaves a widget (or 
enters the central area) is quite simple: to make keyboard shortcuts work. In 
the past we had a ton of issues where shortcuts stopped working once you 
entered any text into a textbox. They came back when you clicked on certain 
parts of the gui to give back keyboard focus to the whole program. Those were 
dark times. What we have now isn't ideal either, but it's better than what 
there was before.
Now, metadata editor is a little special as it both shows the data from the 
selected images as well as allows editing. For that reason it applies your 
entry whenever focus goes away so you don't need to confirm your edit.

For CUDA you have to get an NVIDIA card, there are no alternatives.
