[gentoo-user] NVidia drivers and vanilla kernel Linux 4.7.0 anyone?

[Meino . Cramer]

Hi,

trying the new kernel linux-4.7 (vanilla, downloaded from
ftp.kernel.org) with nvidia drivers 
(Installed versions:  367.35-r1^md(03:00:46 07/30/16)(X driver kms
multilib uvm -acpi -compat -gtk3 -pax_kernel -static-libs -tools
-wayland KERNEL="linux -FreeBSD")).
The kernel compiled fine, the nvidia-drivers does not.

Anuone else with the same problem (read: This has to be
fixed by nvidia/Linus) or am I the only one (so it is
my problem...which does not neccessarily imply that I
know how to fix that ... ;) ???

Best regards
Meino

The file-type icons are still be where they should be, but for some
reason they were no longer associated with their respective
mime types.  I've now solved the problem for them by going to the 'file
association' part of system settings and editing the icons for the mime
types which were missing icons.

The program icons which do not show up in the Quicklaunches haven't
changed on my system.  They also don't show up in the Kmenu, which uses
the same .desktop files -- I didn't realize that before because I
rarely look at the menu.  AFAICS, all the icons that no longer show up
in the menu or the launchers are in /usr/share/pixmaps/.  I can use
kmenuedit, which I think edits the .desktop files, to select the icons
which should be displayed, but they're still not displayed.

Agree, you'd need to be fairly large-scale to have their issues, but I
think the article was something anybody interested in databases should
read.  If nothing else it is a really easy to follow explanation of
the underlying architectures.

I'll probably post this to my LUG mailing list.  I think one of the
Postgres devs lurks there so I'm curious to his impressions.

I was a bit surprised to hear about the data corruption bug.  I've
always considered Postgres to have a better reputation for data
integrity.  And of course almost any FOSS project could have a bug.  I
don't know if either project does the kind of regression testing to
reliably detect this sort of issue.  I'd think that it is more likely
that the likes of Oracle would (for their flagship DB (not for MySQL),
and they'd probably be more likely to send out an engineer to beg
forgiveness while they fix your database).  Of course, if you're Uber
the hit you'd take from downtime/etc isn't made up for entirely by
having somebody take a few days to get everything fixed.

Agreed. The posted example partition tables (PT) were just an attempt

OK, my problem is I do not know exactly what this looks like. I am
assuming I can do it all with gdisk (which is gptfdisk right)?

So this is just a starting point of what the PT & fstab cold look like

Number  Start   End SizeType File system Flags
 1  1049kB  211MB   210MB   primary  ext2boot
 2  211MB   139GB   138GB   primary  linux-swap(v1)

OK, I was already thinking about placing /boot under '/' anyway, as
many of the stage-4 images I will be using in the auto-image installs
are commonly found as using just 2 partitions anyway ('/' and swap)

The '/usr/local' will be optional depending on disk size and available 
space to provide this third partition. /usr/local will not be needed for 
boot(strap) and can be mounted after the systems is up. So /boot

is part of / now.

Yep, I just 'dogged' the PT hoping someone would create and post what it
should look like, or copy/paste a correct example from somewhere. Sorry

I'm going to do away with a separate /boot for now and 'boot' partition 
will be moved under /.

Well, proper alignment was automatically taken care of with newer tools?
That sort of perfromance issue is also critical. Eventuall, SSD and usb3
mmc and all sorts of other media will be used, depending on the embedded
board's supported interface mix that will work with the vendor's (board) 
bootstrap code to bring up linux.

Is this true if one is using grub-legacy?

While I'm at it (gentoo specific) what is the difference in 
sys-boot/grub-static (0.96-r1 to  0.97-r12) and sys-boot/grub (0.97-r16)

in slot zero?

I'm assuming that sys-boot/grub-2.02_beta2-r9++ is all grub-2 with 
current enhancements.



I do appreciate all the inputs, and appologize again for the 
transitioning emails, complicated by the demise of gmane.org (my fav 
reading/posting for gentoo-user).


I'm going to post back as soon as I get an actually 2T disk setup with
all of this advise, just to check what folks think and eventually with
the results of booting a variety of mbr systems (efi and newer embedded 
systems as they are purchased.)


I have a few SSD to experiment with now and may try some usb devices
after the spinning rust PT is happy.

It can be changed. SSDs are best used with 512B sectors. But, err...

The protective MBR can point to another one and you can select which
GPT partitions are in it. But that's getting into some rube goldberg
action.

The place to start with troubleshooting is with some creative investigation.

`genlop -l --date "2016/07/28"` will show you all packages installed in the 
last 2 days - grep the output for "icon" and "theme".

Use `eix -I icon` to see what relevant packages are installed on your system. 
Now the same for `eix -I theme`.

If any of the installed icon or theme packages have not been updated in the 
last 2 days, update them.

I speculate that kde-plasma/plasma-desktop depends on packages X and Y, and 
between -5.5.5 and -5.6.5 some icons were moved from one package to the other.

Surely there are things you can try before posting here. I feel unkind saying 
this, so I apologise, but at the least you could have posted a list of the 
packages that you installed yesterday. 

Half the time I sit down to ask a question here, I solve it myself during the 
process of documenting the bug to explain my problem to the list (see ESR's 
"How To Ask Questions The Smart Way"). It's appropriate to work out what 
installed packages might be relevant, update them to the latest versions, and 
show the list that you've done this.

I think that if none of this works, it would be sensible to see if you can 
downgrade some relevant the packages that you installed yesterday (i.e. those 
with "icon" or "theme" in the name), and see if this reinstates your visual 
file-type portrayals. This is a bit more work, but it might document the 
problem sufficiently that you can document the bug at b.g.o. and help others.
