[gentoo-user] Gaming on gentoo

[Alan Ianson]

Hello list,

I am a gentoo newbie. I have installed gentoo about a month ago and have been 
busy since in my free time getting it up and running.

I have a problem with quakespasm, it segfaults on startup.. this is what I get..

alan@irondust:/usr/share/games/quake$ quakespasm
Command line: quakespasm

alan@irondust:/usr/share/games/quake$ 

I get the above with version 0.95.1 (installed from guru using the git version) 
and from 0.94.1 also from guru.

I am not sure why it segfaults or what I can do about that. I have built it 
with sdl and sdl2 and I get the same result.

I have run quakespasm on other distributions like debian, archlinux and 
slackware without issues so there may be something different about gentoo that 
I need to know about.

Any thoughts or ideas about how to get this working would be appreciated.

You've done it again! What a fine effort. It's saved me much wailing and 
gnashing of teeth.

Is there any chance of enabling gpm to work with it? That would save yet more 
generations of tooth enamel.  :)

Seriously, though, it's just wonderful as it is, and we all owe you a debt.

Well, when I ran into the permission problem, I was going to start over
anyway.  Figured if I was going to start over, may as well switch to
TrueNAS while at it.  So, I switched.  I only used FreeNAS because it
was the first one I found.  It was put on the USB stick ages ago. I'm
keeping a eye out for a small hard drive, 250GB or something to use as
the OS drive in the NAS.  I've read it wears out USB sticks pretty fast. 

At first, I couldn't get both drives to add at the same time.  To work
around that, I set up a pool with one drive.  I then went back and added
the second drive.  Then it was both drives added together, like I do in
LVM.  Then I did the file system thing, dataset I think they call it??? 

After a while, I shutdown the NAS.  I got on Ebay and ordered a 1GB
network card.  Everything I have is 1GB so no need getting anything
faster.  It should be a lot faster and may be about all the NAS rig can
handle anyway.

I haven't figured out how to encrypt it yet tho.  I need to research that. 

Still, progress.

Congrats on making progress.

Is this still FreeNAS or did you switch to TrueNAS Core?

Yeah, 100Mb/S, or say 12MB/S takes days to move
multiple Terrabytes. I did it inside of a screen session so that
I could disconnect and leave it running in the background
without having to watch cold molasses flow. I'm looking
to upgrade everything to 2.5Gb/S or higher one of these
days but once the initial backup is done regular backups
are reasonably fast.

I was disappointed in the info Frank found about not being
able to bond Pools, but it still makes me wonder if someone
could create a 14TB RAID0 outside of the pool and then bond
that RAID0 with a 14TB drive to make a 14TB ZFS RAID1.

Not looking to do it myself though... ;-)

  It still dies on the media-libs/babl-0.1.96-r1 build.  The only change
is that launching "emerge --changed-use --deep --update @world" says 11
items to build, rather than 10.

Thanks for the testing!  6.1 _is_ up to date.  :-)

Many thanks for this.

I can confirm that it patches, compiles and works on 6.1 :)

Re: [gentoo-user] Soft scrolling on framebuffer consoles - New version of the patch.

[Alan Mackenzie]

Hello, Gentoo.

Here is the latest version of my soft scrolling patch for the gentoo
kernel version 5.15.80.  It will surely work on any reasonably recent
kernel version, and also on future versions.  The new version doesn't
add any new functionality, it just patches the kernel giving rise to
fewer messages from the patch utility.

The purpose of the patch is to enable you to scroll a linux console text
display up and down by half a screen by typing  and
.

To use this patch, proceed thusly:

(i) cd /usr/src/linux-5.15.80, or similar.  Get the attached patch file,
  5.15.80-scroll-20221212.diff into this directory.
(ii) patch -p1 < 5.15.80-scroll-20221212.diff.
(iii) Configure the kernel in your usual way.  The extra items added by
  the patch are CONFIG_FRAMEBUFFER_CONSOLE_SOFT_SCROLLBACK and
  CONFIG_FRAMEBUFFER_CONSOLE_SOFT_SCROLLBACK_SIZE, to be found in make
  menuconfig under Device Drivers/Graphic Support/Console display driver
  support.  The help items for these should explain them adequately.
(iv) Build the kernel.
(v) Put the new kernel into your usual boot manager.
(vi) Reboot and enjoy!

As far as I know this patch should be safe (apart from the mysterious
alleged security problem which caused the soft scrolling to be removed
from the kernel in the first place).  There is certainly nothing
malicious in it.  But if it does break anything for you, you get to keep
the pieces.  But if anything does go wrong, please tell me about it
(preferably here on the list, but by private email if you'd prefer), so
that I can try and fix it.

I don't know about the UTF8 error and if it is related to your failure, but 
since it complains about the vala compiler, it may be worth rebuilding it 
first?

  No change.  dev-libs/glib-2.74.1-r1:2::gentoo was a straight rebuild;
no upgrade; no USE-flag changes; and the babl compile still dies.  What
is the "GLib-CRITICAL" bit about PCRE with no UTF8 support?

You should try to first upgrade/rebuild the dev-libs/glib package.
