Based on the reading I did you probably want
https://github.com/ipts-linux-org/ipts-linux-new, which supports
kernels after 4.4. There was a change made to the DRM subsystem that
broke everything.

It looks like the usability is very closely related to the usability
of OpenCL on Intel iGPUs. This is unfortunate, I suppose. I'm not sure
if they're literally transcribing what they received from the OEM or
if the touch hardware is bussed to the iGPU for some reason.

  I believe that postgresql 32-bit is different internally from 64-bit.
You have to do a dump+restore or some other form of data copy or synch.
You cannot take the 32-bit data tables and run under 64-bit postgresql
(or visa versa).

Thanks James, but the pro4 has different hardware to the pro3 (first
article) and I am running gentoo on it.

The Y2K fixes for systems which could not have old data modified
simply treat the imprecise/truncated date field as happening before
the event that necessitated the fix.

You don't have to change any of your files, and updating the programs
can happen in place.

Nevertheless, I did only follow an instruction in a Gentoo wiki page. It 
said the change was "for future compatibility" or some such. I wouldn't just 
have made it up for myself.

This is the easy way:

 1) Back up user data (e.g. home directories) and system config files
(e.g. /etc/)
 
 2) Install from scratch
 
 3) restore user data and config files.

It's not just the kernel.  If you want to avoid the 32-bit time
problem, then you need to re-install all of the user-space librairies
and binary exectuables that use the time() libc function.

That's ridiculous.  You're configuring the main portage tree to be a master of 
itself.  Search 
for "masters" in portage(5) for an explanation of what that option is for (it's 
mainly 
interesting for overlays).

What probably happened is that this is the first time something changed in 
layout.conf since 
you added the "masters" line, thus why git never complained.

Since git is a version control system, it won't blindly overwrite local 
changes, so it's best not 
to make any :) (so don't add that change back in, since it's pointless anyway). 
 Always use 
your own overlay if you want to make changes.

You can check if the firmware is included in the kernel config:

grep -i wifi /usr/src/linux/.config

If CONFIG_EXTRA_FIRMWARE is set, then a firmware is included. You just
need to check if it's the right one for your wifi chip.

Otherwise you can set some options in /etc/genkernel.conf.

Set MENUCONFIG="yes" to be able to configure your kernel by yourself
and set CONFIG_EXTRA_FIRMWARE there.

Or instead you can set those options in /etc/genkernel.conf:
FIRMWARE="yes"
FIRMWARE_DIR="/lib/firmware"
FIRMWARE_FILES=""

I have't tried the latter, because I usually configure my kernel by
myself with menuconfig. I only use genkernel as an easier way to have
the kernel compiled, installed and the initrd built.

It showed me that I'd changed "masters =" to "masters = gentoo" in 
layout.conf, which I knew because I'd been told to at some time. But I did 
that ages ago, long before my last sync yesterday, so what else has changed? 
I didn't emerge anything yesterday, as confirmed by "grep completed

git-checkout(1) has a '--theirs' option that might do the trick there:

The index may contain unmerged entries because of a previous failed
merge. By default, if you try to check out such an entry from the
index, the checkout operation will fail and nothing will be checked
out.
...
You could try:
git checkout --theirs metadata/layout.conf

"git reset --hard" to reset the repository should solve that problem.

As already pointed out, this driver does require firmware to run. See below.

drivers/net/wireless/intel/iwlwifi/Kconfig:1,31
config IWLWIFI
tristate "Intel Wireless WiFi Next Gen AGN -
Wireless-N/Advanced-N/Ultimate-N (iwlwifi) "
depends on PCI && MAC80211 && HAS_IOMEM
select FW_LOADER
---help---
 Select to build the driver supporting the:

 Intel Wireless WiFi Link Next-Gen AGN

 This option enables support for use with the following hardware:
Intel Wireless WiFi Link 6250AGN Adapter
Intel 6000 Series Wi-Fi Adapters (6200AGN and 6300AGN)
Intel WiFi Link 1000BGN
Intel Wireless WiFi 5150AGN
Intel Wireless WiFi 5100AGN, 5300AGN, and 5350AGN
Intel 6005 Series Wi-Fi Adapters
Intel 6030 Series Wi-Fi Adapters
Intel Wireless WiFi Link 6150BGN 2 Adapter
Intel 100 Series Wi-Fi Adapters (100BGN and 130BGN)
Intel 2000 Series Wi-Fi Adapters
Intel 7260 Wi-Fi Adapter
Intel 3160 Wi-Fi Adapter
Intel 7265 Wi-Fi Adapter
Intel 8260 Wi-Fi Adapter
Intel 3165 Wi-Fi Adapter


 This driver uses the kernel's mac80211 subsystem.

 In order to use this driver, you will need a firmware
 image for it.

Also, see this Gentoo wiki article for instructions on how to set up
your driver:
https://wiki.gentoo.org/wiki/Iwlwifi

Re: [gentoo-user] genkernel iwlwifi WiFi driver

[Rasmus Thomsen]

Hello,

you could test if iwlwifi was included by running "modprobe iwlwifi" ( as root 
). If it is included but wifi still doesn't work you might have to install the 
relevant firmware ( via emerge linux-firmware )

[gentoo-user] genkernel iwlwifi WiFi driver

[Radoje Stojisic]

Hello everyone,

I've installed Gentoo on my ThinkPad T460p couple of times. For some 
reason I can't get the WiFi working. I did the installation with 
SystemRescueCD because I needed working WiFi for the install.


So here comes the question:

I've installed the Genkernel. Does Genkernel enables the iwlwifi driver 
automatically? Or do I need the modify the kernel on my own? I've 
installed Gentoo with KDE. iwconfig showed no wifi interface.



Thanks for any advice.

Will there be any fix until then, or will I have

Is there actually a "how-to" to replace a 32-bit-Gentoo by a 64-bit-
Gentoo? Do I have to format the harddisk (and rebuild everything from
scratch), oder can I just keep all the (postfix, apache...) configuration
