Hello Gentoo people,

I am to embark on next step of gentoo rpi experiance,
so this link draw my eye: https://github.com/sakaki-/gentoo-on-rpi-64bit/wiki/Improve-Swap-Perfomance-on-your-RPi
but I am confuse by this:
Code:
demouser@pi64 ~ $ sed 's:\s*#.*$::g' <<EOF | sudo fdisk /dev/sdX
o  # create a new DOS partition table
n  # then create a new partition
p  # which is primary
1  # and is partition 1
   # use the default start sector
   # and default end sector, to fill the drive
t  # change the partition type
82 # to 'Linux swap'
w  # then commit changes and exit
EOF

How is this executed?
I mean is this 11 commands in terminal? eof is end of file, do I have to write those down in some file?
and is it wrong if i just go sudo fdisk /dev/sdX, and when fdisk opens, i issue the o's and n's and p's in that written order?

Thank you

According to that GitHub wiki article:
Quote:
In the above, sed is used simply to strip out all comments on each line, before passing to fdisk.

So you may also choose to manually type those commands in fdisk instead of running them automatically. At least that's what I would choose to do myself.
I also think you can use parted instead of fdisk if you are more familiar to the former.

hello fturco,

thank you, that was not clear to me, I did it as you suggested, it is just strange to see instructions in that way.

ok, i have 4g swap on usb, thanks


Now I hit another issue, I use dwm, with .xinit, but instead of a usual blink of an eye from startx to wm, it takes over 20 seconds?

Thank you

while true,

Pastebin /var/log/Xorg.0.log please so we can see what Xorg is doing as it starts.

dmesg may be useful too.

Hello NeddySeagoon,

I am still havinf wifi prolems also,
i'll use usb-wifi dongle to get on network, emerge wgetpaste and i'll get right back
thank you


EDIT:
Well it seem that was couple off, maybe that usb-swap thing needed setteling.
I just rebooted 3 times, and each time I startx-ed 2-3 times, and all is done in a blink of an eye, so I am sorry for screaming...
Code:
|--------------->
~/# wgetpaste /var/log/Xorg.0.log
Your paste can be seen here: http://dpaste.com/2R1KM9K
|--------------->
~/# dmesg | wgetpaste
Pasting > 25 kB often tend to fail with dpaste. Use --verbose or --debug to see the
error output from wget if it fails. Alternatively use another pastebin service.
Your paste can be seen here: http://dpaste.com/381BC3C
|--------------->

thank you

X fails due to the following error:
Code:
[    42.910] (II) modeset(0): Refusing to try glamor on llvmpipe
[    42.913] (EE) modeset(0): glamor initialization failed

It seems this behavior has been introduced with this git commit.

Did you configure Xorg manually perhaps? If so, please show us the contents of /etc/X11/xorg.conf and/or the contents of the files in /etc/X11/xorg.conf.d.

Output from the following commands would be nice, too:
Code:
emerge --info
emerge -pv xorg-server

Hello fturco,

I was thinking about opening a new thread for this problem, since it repeted itself today, but than, again, disappeared, I tell you, it is a roller-coaster here, I can not seem to get any consistent output...

So yes, please, I'll start new thread with output you requested,
(link: https://forums.gentoo.org/viewtopic-t-1104578.html)
and this thread will need updating soon, i feell...
