I elaborated elsewhere on this forum but since you think I'm a moron I'll do so here as well.

Call it absurd if you want, but I was completely put off by the fact that a fresh Slackware 14.2 outright freezes at boot on my desktop.

It never finishes init, never reaches the login prompt, leaving me no choice but to find another means by which to blacklist the nouveau driver, only then does it start working. The alternative would be to remove my dedicated GPU so it stops choking on that long enough to blacklist it before reinstalling. Not happening.

The desire to reinstall an OS that out of the box does not function on my hardware doesn't exist.

So yes, when I broke 14.2 in an unrelated event, I wasn't about to reinstall it and go through that nonsense again.

Current gets to the login prompt and allows me to take care of business.

Also when quoting me you left out the 'for fun' part, as if I was doing this as a serious project for me or something. If this wasn't fun I would be running Windows 10 right now.

Thank you and good night.

I don't think you're a moron at all, I just didn't understand your reasons and didn't think to look elsewhere to see if you had provided them [though it's not my responsibility to do so]. Anyone who runs [or seriously attempts to run] Slackware can't be a moron. That's one of the beauties of this forum.

Hmm OK, again, you have given some scant leading information but not elaborated on it in the same post. Still, never mind. Speaking from personal experience, I broke my 14.2 install about ten times before I got it to work. And that's only because the issues were mine and mine only, it wasn't Slackware's fault.

Yes, I left that off because it lent more validity to my point. Also, getting Slackware to work properly should be seen as a slightly serious undertaking, I would have thought, since it's not really a click-and-go distro [again, I'm not saying that you think it is such, I'm only pointing out the differences].

Right, apologies for getting worked up, that was uncalled for on my part.

I don't fault Slack either, 14.2 runs perfectly on several other machines I have lying around here.

I see. Thank you.

Sorry, it's just a saying we have here for when we end a rant or tirade.


I don't take issue with the philosophy of using older but more mature versions of software as opposed to cutting edge.. I mean we are talking about Slackware after all.

I think part of my internalized rationale for thinking newer would be better also came from the much newer kernel versions that current runs, with the spectre and meltdown vulnerabilities in my mind. Though perhaps I misunderstood and kernel 4.4.x that 14.2 runs has been patched to mitigate that.

ReFracture, I have to say that's one of the most mature responses I've ever seen to a [potential] online spat. That's testament to the kind of posters we have in the community here.

Well, it's nearly there on 64bit 14.2. I'm one official revision behind, being on 4.4.153 when the latest official is 4.4.157. Still, this is what 4.4.153 gives me:

Code:
lysander@psychopig-xxxiv:~$ gawk '{ print FILENAME ":\t" $0 }' /sys/devices/system/cpu/vulnerabilities/*
/sys/devices/system/cpu/vulnerabilities/l1tf:	Mitigation: Page Table Inversion
/sys/devices/system/cpu/vulnerabilities/meltdown:	Mitigation: PTI
/sys/devices/system/cpu/vulnerabilities/spec_store_bypass:	Vulnerable
/sys/devices/system/cpu/vulnerabilities/spectre_v1:	Mitigation: __user pointer sanitization
/sys/devices/system/cpu/vulnerabilities/spectre_v2:	Mitigation: Full generic retpoline
lysander@psychopig-xxxiv:~$
I'll patch all my systems probably when the next official kernel upgrade comes along. Though I'm tempted to keep my netbook on 4.4.153 for the foreseeable future because the kernel provides excellent battery life for that machine [not ideal I know, but I'll play it by ear with that computer].

The only extra installed package, that might be related or not, is OpenAL.
To get kernel support for my vega64 graphics I "rolled my own".
Stock config will not work with amdgpu dal code and it is still finnicky, It spews a long stack trace in the
kernel log from something that crashes when kms starts. Originally it would not work at all.
Disabling "AMD Secure memory encryption" (after a tip from the gentoo site) finally got it going
and it seems to function as good as any other driver, in spite of the mentioned stack trace.
Doom on our system, performance wise, is somewhat behind win10. Vulkan is a must!
I can play with everything cranked to absolute maximum in 4k with framerates always > 70 fps on w10.
On our system with the "steamplay" in between it drops to about 45-50 fps, but reducing
resolution to 2.5k gets framerates back up to 90 fps and a very playable game.
Default Doom settings is to use opengl which sucks even at 1920x1080 (45 fps), and you, like me, will probably
not have much luck changing api settings once Doom is started.
The solution is to edit launch options. Just add +r_renderapi 1 and you're home.

Slackware 64-current will not start X with my Ryzen 3 2200U, Vega 3. Thanks, I think that is it and is causing all kinds of problems in other distros.

The amdgpu dal/display for vega is a long way from mature it seems.
I'm still having mile long crash traces in the kernel log on all my
machines as soon as it loads. Disabling it (amdgpu.dc=0) solves the
issue on older non-vega hw. You can always try passing
mem_encrypt=off
to the kernel, and pray
I'm not even sure AMD sme is enabled by default, so what difference it makes
is dubious.
I excluded AMD sme completely when i recompiled for my vega10 on an AMD 9590.
It seemed to help im my case.
good luck!

I don't think that Ryzen APUs were supported in the 4.14 kernel used in -current. It was likely bundled into the 4.15 AMDGPU DC update (along with likely updates in the newer versions). Hopefully the 4.19 kernel will get officially tagged as LTS soon and Pat will incorporate that

FYI, you might have problems with the latest 3.16-1 build: https://github.com/ValveSoftware/Proton/issues/1730

And, as a workaround for Proton 3.16-1: in /usr/bin/steam (assuming you're using Alien Bob's package): STEAM_RUNTIME_PREFER_HOST_LIBRARIES=1

Downside is that you don't get the spiffy Steam icon in your taskbar.

If you need the transform feedback patches to dxvk, you'll need to upgrade vulkan-sdk and your video card drivers, I think, but I don't have any games (witcher 3) that needs it via Steam.

It's been a while since I've used steam, but I believe you can put any environment variables you want to run steam against in a ~/.steam4slackware file.
