=====Install a .txz package from a local directory=====
<code>

</code>

=====Slackware 14.0=====

====Re-enabling the huge.s kernel on 14.0/14.1 after an update resets it to hugesmp.s====
// Note: this may or may not be the best way to do it, but it worked for me. //

Scenario:\\
  * You install Slackware 14.0/14.1 i386 from DVD on a non PAE capable system (Acer Aspire 9500, Pentium M 735).
  * You use slackpkg update followed by slackpkg upgrade-all to upgrade all packages including the kernel (to 3.2.45/3.10.103).
  * On reboot you are greeted with the message:<code>This kernel requires the following features not present on the CPU:
pae
Unable to boot - please use a kernel appropriate for your CPU.</code>

Fix (when using the huge.s kernel):
  - Boot from the Slackware DVD matching the version of Slackware that is installed.
  - At the boot: prompt boot your system with:<code>huge.s root=/dev/sda1 rdinit= ro</code> // Change /dev/sda1 to the hard disk where Slackware is installed. //
  - Log in as root.
  - Change directory to /boot:<code>cd /boot</code> // If you execute ls -l here you'll see that System.map, config, and vmlinuz are symbolic links to the huge-smp kernel, which is not the kernel you want. //
  - Remove System.map, config, and vmlinuz:<code> rm System.map config vmlinuz</code>
  - Create new symbolic links to the huge kernel:<code>ln -s System.map-huge-3.2.45 System.map
ln -s config-huge-3.2.45 config
ln -s vmlinuz-huge-3.2.45 vmlinuz
</code> // Change 3.2.45 to the new kernel version. //
  - Run lilo without parameters:<code>lilo</code> // Don't forget to do this as it will still boot the old kernel if you don't. //
  - Reboot.

Fix (when using the generic kernel and a custom initrd): \\
// For example when you followed README_LVM.TXT for enabling LVM support. //
  - Boot from the Slackware DVD matching the version of Slackware that is installed.
  - At the boot: prompt boot your system with:<code>huge.s</code>
  - Log in as root.
  - Start setup:<code>setup</code>
  - Go to TARGET. // This is used to quickly make the LVM lvs visible. //
  - Exit from setup
  - Mount the lvs. Example:<code>
mount /dev/mapper/root--vg-root /mnt
mount /dev/mapper/root--vg-usr /mnt/usr
mount /dev/mapper/root--vg-var /mnt/var
mount /dev/mapper/root--vg-tmp /mnt/tmp
mount /dev/mapper/root--vg-home /mnt/home
mount /dev/sda1 /mnt/boot
</code>
  - Chroot to /mnt:<code> chroot /mnt</code>
  - Change directory to /boot:<code>cd /boot</code> // If you execute ls -l here you'll see that System.map, config, and vmlinuz are symbolic links to the huge-smp kernel, which is not the kernel you want. //
  - Remove System.map, config, and vmlinuz:<code> rm System.map config vmlinuz</code>
  - Create new symbolic links to the generic kernel:<code>ln -s System.map-generic-3.10.103 System.map
ln -s config-huge-3.10.103 config
ln -s vmlinuz-huge-3.10.103 vmlinuz
</code> // Change 3.10.103 to the new kernel version. //
  - Create a new initrd:<code>mkinitrd -c -k 3.10.103 -m ext4 -f ext4 -r /dev/root--vg-root -L</code> // Change 3.10.103 to the new kernel version. //
  - Edit /etc/lilo.conf to boot the new kernel and initrd. Example:<code>
  image = /boot/vmlinuz-generic-3.10.103
    initrd = /boot/initrd.gz
    root = /dev/root--vg-root
    label = Slackware
    read-only
</code> // Change 3.10.103 to the new kernel version. //
  - Run lilo without parameters:<code>lilo</code> // Don't forget to do this as it will still boot the old kernel if you don't. //
  - Reboot.

=====Slackware 14.1=====

====Updating====
  - Edit /etc/slackpkg/mirrors and uncomment the line for the geographically closest mirror.
  - Update the list of (updateable) packages with: <code>slackpkg update</code>
  - Upgrade the packages with: <code>slackpkg upgrade-all</code>
  - Don't forget to install new packages: <code>slackpkg install-new</code>
  - // And (only) when following Slackware current: (re)install multilib to get newly added compat32 packages. // <code>slackpkg install multilib</code> // Reinstalling multitlib this way requires that [[os:linux:distributions:slackware:notes#installing_slackpkg|slackpkg+]] is installed. //


====NVIDIA Graphics drivers for GeForce 6800 GT====
// See: [[http://www.nvidia.com/object/IO_32667.html|NVIDIA - What's a legacy driver?]] for a list of which driver version to use for which graphics card. //

Download the NVIDIA-Linux-x86-304.125.run (or NVIDIA-Linux-x86_64-304.125.run for Slackware64).

// Don't use the 304.88 version. It will not compile the NVIDIA kernel module and complain about "Kernel configuration invalid" and missing include/generated/autoconf.h and include/config/auto.conf files in nvidia-installer.log. //

Install with:
<code>
sh NVIDIA-Linux-x86-304.125.run
</code>
Answer the questions asked by the ncurses based NVIDIA installer.

===Modes for iiyama HM703UT Vision Master Pro 413===
The HM703UT is a 17" CRT monitor capable of more than the defualt 1024x768 resolution that the NVIDIA driver sets.

Edit /etc/X11/xorg.conf after installing the NVIDIA drivers.

Add a Modes line to the Screen section specifying the desired resolutions, like the Modes line in the following example:
<code>
Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
        Modes      "1600x1200" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600"
    EndSubSection
EndSection
</code>

====Installing Slackpkg+====
Slackpkg+ allows installing packages on Slackware from several unofficial repositories.

Download the latest version of Slackpkg+ from [[http://slakfinder.org/slackpkg+.html|Slackpkg+ - A slackpkg plugin for third-party repositories]]. \\
Install with:<code>installpkg slackpkg+-1.4.0-noarch-2mt.txz</code>
Update:
<code>
slackpkg update gpg
slackpkg update
</code>

Steps in VLC (tested with VLC 2.1.5 from alienbob's slackware repo):
  * Open capture device. 
  * Capture mode: Video camera
  * Video device name: /dev/video0
  * Audio device name: hw:2,0
  * Video standard: PAL
  * Advanced options:
  * chroma=YUYV
  * frequency:591000 (VCR is on channel 36, a frequency of 591250 does not work)

This results in the following MRL and options:

=====Slackware 14.2=====


====Booting to graphical login manager====

// After choosing your Windows Manager during installation or with xwmconfig. //

  - su to root.
  - Open /etc/inittab in your favorite texteditor.
  - Change the line<code># Default runlevel. (Do not set to 0 or 6)
id:3:initdefault:</code>
  - To:<code># Default runlevel. (Do not set to 0 or 6)
id:4:initdefault:</code>
  - Reboot the system. It should now start the login manager that belongs to the selected window manager.


====Install ffmpeg for mp4 support in browser (for Disney+)====

On a clean Slackware64 14.2 installation don't forget to install ffmpeg to support the playback of mp4 files (needed for Disney+).

  - Download the latest [[http://slakfinder.org/slackpkg+.html|slackpkg+]].
  - Install slackpkg+ with:<code>su
installpkg slackpkg+-1.7.0-noarch-10mt.txz</code>
  - Edit /etc/slackpkg/slackpkgplus.conf and enable the restricted repository.
  - Update:<code>slackpkg update gpg
slackpkg update</code>
  - Install ffmpeg:<code>slackpkg install ffmpeg</code>
  - Restart the browser if it was running before installing ffmpeg.
  - mp4 files should now be playable within the browser.
    - // And Disney+ should show more than just the Disney+ logo after starting a video. //
