====== Devuan Issues ======

Issues... and maybe fixes (if any).

===== Image Magick's convert error =====

I found an error when using image magick's convert to create EPS from fig that provides this message: <code>convert-im6.q16: attempt to perform an operation not allowed by the security policy `EPS' @error/constitute.c/IsCoderAuthorized/421</code>

Solution:
  * (as root) edit ''/etc/ImageMagick-6/policy.xml''
  * modify following line (change none -> read|write) <code xml><policy domain="coder" rights="none" pattern="EPS" /></code>

===== GRUB Prompt =====

In some cases, after an installation  is complete, the system boots to a GRUB prompt. The issue may be caused by a different disk assignment during installation. Things is not so bad since GRUB prompt is very shell-like (e.g. double-tab for completion):

To list available disks: <code>> ls </code>

To list content of first partition on the first disk (/dev/sda1) that is using GPT: <code>> ls (hd0,gpt1) </code>

So, to boot an installation on second partition instead: <code>
> linux (hd0,gpt2)/boot/vmlinuz<...>
> initrd (hd0,gpt2)/boot/initrd.img<...>
> boot
</code>

===== BCM Wireless =====

Device: 
<code>
# lspci -nn | grep BCM
02:00.0 Network controller [0280]: Broadcom Limited BCM43142 802.11b/g/n [14e4:4365] (rev 01)
</code>

Install: broadcom-sta-dkms, firmware-linux, firmware-b43-installer (b43-fwcutter)

*note*: only solves the Wireless Driver part... NOT the bluetooth hardware!

<code>
# lsusb | grep BCM
Bus 002 Device 004: ID 0a5c:216d Broadcom Corp. BCM43142A0 Bluetooth 4.0
# dmesg | grep blue
[    8.850007] bluetooth hci0: firmware: failed to load brcm/BCM43142A0-0a5c-216d.hcd (-2)
[    8.850197] bluetooth hci0: Direct firmware load for brcm/BCM43142A0-0a5c-216d.hcd failed with error -2
</code>

So, download ''BCM43142A0-0a5c-21d6.hcd'' in [[https://github.com/winterheart/broadcom-bt-firmware/tree/master/brcm|here]] and place it ''/lib/firmware/brcm/'' (create that path if it does not exist).

===== XFCE Desktop =====

  * tapping on my laptop touchpad is NOT working
    * moving around & button clicks are working
    * need to create file ''/etc/X11/xorg.conf.d/90-touchpad.conf''<file text 90-touchpad.conf>Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "Tapping" "on"
EndSection
</file>
  * lid event does not trigger suspend (but manual suspend works)
    * this is a systemd-related aftermath: xfce power manager allows/assumes login to handle lid
    * fix: <code>$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s false</code>

  * issues when logging out/shutdown
    * may be caused by intel graphics library? i915?
    * can install lightdm - but shutdown/restart always gets login page (=logout)
  * wicd feature is an issue for system with multiple users
    * shared wifi password, no option to make private

===== Cinnamon DE =====

  * login page (lightdm?) - cannot shutdown/reboot! read [[https://git.devuan.org/devuan-packages/lightdm/issues/2|here]]...
    * found a fix [[https://dev1galaxy.org/viewtopic.php?pid=11114#p11114|here]]
    * i just needed to edit ''/etc/pam.d/lightdm-greeter'' and changed ''pam_systemd.so'' to ''pam_elogind.so'' (but, may cause issues with suspend/hibernate?)
  * laptop battery quickly drain below 30 percent
    * setup higher critical value for power management <code>
gsettings list-keys org.cinnamon.settings-daemon.plugins.power
gsettings set org.cinnamon.settings-daemon.plugins.power use-time-for-policy false
gsettings set org.cinnamon.settings-daemon.plugins.power percentage-low 30
gsettings set org.cinnamon.settings-daemon.plugins.power percentage-critical 25
gsettings set org.cinnamon.settings-daemon.plugins.power percentage-action 23
</code>
    * or use ''dconf-editor''

===== PulseAudio =====

Youtube videos keep resetting the volume settings to 100%! The culprit is ''flat-volumes''. Modify ''/etc/pulse/daemon.conf'' and set ''flat-volumes=no''.

===== (Re)-Compiling Syslinux =====

I need to recompile syslinux - just to remind myself, other than the usual development packages (build-essential, etc), I also need ''nasm'' and ''upx-ucl''.
<code>apt install nasm and upx-ucl</code>

===== Unwanted Background Program =====

I found this in my old notes... I somehow found an autostart program ''geoclue-demo-agent.desktop'', which I obviously do not need. So, simply remove that from autostart path <code># rm /etc/xdg/autostart/geoclue-demo-agent.desktop</code>

===== Sound muted on startup on my HP laptop =====

trying two options found... so far, not successful? keeping this here for reference.

  - option 1:
    * install alsa-utils
    * make sure sound is not muted and set to desired volume level
    * run (as root) alsactl store
  - option 2:
    * edit (as root) /etc/pulse/defaults.pa
      * can also copy this to home folder ??? for 1-user solution...
    * comment out 'load-module module-device-restore'

===== General Issues =====

  * wifi firmware missing after first restart
    * manually install ''firmware-ralink''
  * network manager cannot connect using wifi
    * edit /etc/NetworkManager/NetworkManager.conf
    * add <code>
[device]
wifi.scan-rand-mac-address=no
</code>
