Running 22.04 system dual NICs - clean installed 26.04 LTS Desktop. Now no network forwarding happenning https://askubuntu.com/questions/1566727/running-22-04-system-dual-nics-clean-installed-26-04-lts-desktop-now-no-netwo

I was Running 24.04 system. Dual NICs - one to WAN, other to LAN.
Firefox, Thunderbird etc. all working on Windows10 machine attached to LAN.
DHCP, name, samba, iptables servers all working in the Linux box.

Then I did a full backup of the linux box, cleaned and formatted a drive I was using as a mirror for the root disk (only system, no data stored on root disk).

Then I did clean install of 26.04 LTS desktop on that clean disk from a USB stick, installed the netplan 00*.yaml file from my backup shown below.

# This is the network config written by 'subiquity' then edited
network:
  ethernets:
# LAN
    enp3s0:
      dhcp6: false
      dhcp4: false
      addresses:
      - 192.168.1.16/24
      nameservers:
        addresses:
        - 10.0.0.138
        search: []
      routes:
      - to: default
        via: 10.0.0.138
# WAN 
    enp4s0:
      dhcp6: false
      dhcp4: true
  version: 2

Replacing the default file installed from the USB stick.
Then installed the isc-dhcp-server and replaced the conf file with the one from my backup.

=================================================

Tried running sysctl -w net.ipv4.ip_forward=1 and got the response "Cannot find /etc/system.conf", (that's where a lot of answers to an ip_forward question here said to find it), noted that in /etc/systemd, there is a system.conf file, so I put a symbolic link in /etc called system.conf pointing at that file in /etc/systemd thinking that there had been some error in the upgrade.
entered
sudo sysctl -w net.ipv4.ip_forward=1 and
sudo sysctl -p

then ran this script I use for debugging network setups. Just a list of iptables commands which has resulted in unimpeded traffic WAN <--> LAN in the past.
#!/bin/bash
#
# iptablesOpen.sh
#
echo "Opening firewall and allowing everyone ..."
#
iptables -t filter -F
iptables -t filter -P INPUT ACCEPT
iptables -t filter -P FORWARD ACCEPT
iptables -t filter -P OUTPUT ACCEPT
#
iptables -t nat -F
iptables -t nat -P PREROUTING ACCEPT
iptables -t nat -P INPUT ACCEPT
iptables -t nat -P OUTPUT ACCEPT
iptables -t nat -P POSTROUTING ACCEPT
#
iptables -t mangle -F
iptables -t mangle -P PREROUTING ACCEPT
iptables -t mangle -P INPUT ACCEPT
iptables -t mangle -P FORWARD ACCEPT
iptables -t mangle -P OUTPUT ACCEPT
iptables -t mangle -P POSTROUTING ACCEPT
#

At this point Firefox on the Linux box accesses the WAN and servers such as Amazon with no problems. Running 'tail -f /var/log/syslog' displays the network traffic on the LAN involved with the DHCP server doing its job for the attached Windows 10 desktop.

BUT NO traffic is forwarded through the linux box between the LAN and WAN.

aarnet.edu.au is a VERY reliable server attached to Melbourne University (Australia) but
ping aarnet.edu.au entered on a Windows command line responds with 'cannot reach server' . The same command entered into the linux box receives the expected answers, complete with an IP address but typing 'ping 202.158.207.3 at the Windows command line returns the same negative response.

What have I done wrong?

PCSX2 BIOS Not Detecting on Ubuntu After Installation https://askubuntu.com/questions/1566725/pcsx2-bios-not-detecting-on-ubuntu-after-installation

I recently installed PCSX2 on Ubuntu to play some old PS2 games, but the emulator is not detecting the BIOS files correctly. I already copied the BIOS files into the default folder and tried rescanning multiple times, but the BIOS list still appears empty.

I also tested:

  • changing BIOS folder location

  • updating emulator packages

  • checking file permissions

  • reinstalling PCSX2

Sometimes the emulator launches, but games either show a black screen or crash during startup.

While searching for setup help, I found this guide: Download ps2 bios

but I’m still trying to understand whether this is a Linux permission issue, wrong BIOS version, or emulator compatibility problem.

Has anyone fixed this issue on Ubuntu recently?

Ubuntu 24.04 on Z890 AORUS Elite WiFi7: slow desktop, delayed app launch https://askubuntu.com/questions/1566724/ubuntu-24-04-on-z890-aorus-elite-wifi7-slow-desktop-delayed-app-launch

I recently built a new desktop PC and installed Ubuntu 24.04. After installation, the desktop is noticeably sluggish.

Problem

After logging in, I sometimes see a black screen for a few seconds with an X-shaped cursor before the desktop appears.

Once I enter the desktop, the system feels slow:

  • Opening Files, Terminal, Chrome, or VS Code can take around 10–20 seconds.
  • Sometimes the Files app becomes unresponsive.
  • The mouse cursor can still move, but the desktop UI feels delayed.
  • I tested both X11 and Wayland, but the lag still happens.
  • This is a fresh Ubuntu installation on a new PC.

I am trying to determine whether this is caused by the NVIDIA driver, kernel, GNOME desktop/session, SSD, BIOS settings, or hardware compatibility.

System information

  • Ubuntu version: 24.04.4 LTS
  • Kernel Version: 6.17.0-23-generic
  • NVIDIA driver version: 595.58.03
  • CUDA Version: 13.2

Hardware

  • CPU: Intel Core Ultra 7 270K Plus
  • Motherboard: Gigabyte Z890 AORUS ELITE WIFI7 ICE
  • RAM: Kingston Fury Beast 32GB x2 DDR5-6400, total 64GB
  • GPU: Gigabyte AORUS GeForce RTX 5090 MASTER ICE 32GB
  • SSD: Kingston KC3000 4TB PCIe 4.0 NVMe
  • HDD: Seagate 4TB HDD, ST4000DM004

Dual boot: can I increase my Linux file system even though Windows partitions are in the way? https://askubuntu.com/questions/1566717/dual-boot-can-i-increase-my-linux-file-system-even-though-windows-partitions-ar

I am quite new at Linux. A while ago I made my laptop dual boot and I was a bit stingy on how much space I allocated to Linux. When I had some hardware issue, my computershop replaced my 500GB SSD with a 1TB SSD, but just cloned the old partitions on it.

These are the partitions:

Device          Start             End      Sectors         Size  Type
/dev/nvme0n1p1        2,048       534,527       532,480    260M  EFI System
/dev/nvme0n1p2      534,528       567,295        32,768     16M  Microsoft reserved
/dev/nvme0n1p3      567,296   759,959,809   759,392,514  362,1G  Microsoft basic data
/dev/nvme0n1p6  759,961,600   957,476,863   197,515,264   94,2G  Linux filesystem
/dev/nvme0n1p4  957,476,864   959,320,063     1,843,200    900M  Windows recovery environmen
/dev/nvme0n1p5  959,320,064 1,000,214,527    40,894,464   19,5G  Microsoft basic data

Sum of sectors   1,000,210,690      
Physical sectors 1,953,525,168      

I rearranged p6 to its actual place in the SSD.

So when I followed the instructions to enlarge partition 6, I was surprised to find that it hadn´t worked even though there were no errors. The reason became obvious once I studied this table: there is no unallocated space behind the Linux filesystem; 2 windows related partitions are in the way.

I'm not sure how to solve this. I would like to increase the Linux partition but I'm not sure if it is possible to do that non-contiguously. Do I need to reorder these partitions? Is that possible?

Firefox appears in all desktops https://askubuntu.com/questions/1566716/firefox-appears-in-all-desktops

When I try to use multiple desktops to arrange the opened windows, the window of Firefox is present in all of them, even the last one, which is usually totally empty (and when we drag a new window in it, a new empty desktop is created).

You can find attached screenshots of my three desktops, where Firefox appears (I blurred all info that could be sensitive, I hope I did not miss any !).

Desktop 1 Desktop 2 Desktop 3

Note that the Firefox window is the same everywhere: if I change tab or close it, the same result occurs in the windows of other desktops.

I'm using Ubuntu 24.04.

Headless setup not reachable by SSH https://askubuntu.com/questions/1566715/headless-setup-not-reachable-by-ssh

I am trying to build a server using ubuntu server with very low power consumption. The specs are:

Asrock H610M-HVS/M.2

Intel i3 12100F

some NVME SSD

Ubuntu Server 26.04 LTS

And that's it. I can successfully boot into ubuntu if i connect a GPU and use SSH, but I really don't want to have it installed permanently. I have set up a static IP address. Could it be an ubuntu issue, i.e. its POSTing fine but not booting?

Asrock support says it works with Windows, default BIOS settings, so I tried:

sudo systemctl set-default multi-user.target

Didn't work.

I thank everyone in advance, every answer is welcome!

Why I can't install GOfuncR in Ubuntu 24.04?

Unable to do-release-upgrade from 22.04 to 24.04: package guile-2.2-libs held back https://askubuntu.com/questions/1566712/unable-to-do-release-upgrade-from-22-04-to-24-04-package-guile-2-2-libs-held-ba

I'm running ubuntu 22.04.05, trying to upgrade to 24, but apt tells me "Please install all available updates for your release before upgrading.". When I try using apt to upgrade, it tells me that guile-2.2-libs has been held back. When I try "apt list --upgradable -a", it responds

guile-2.2-libs/jammy 2.2.7+1-6build2 amd64 [upgradable from: 2.2.7+1-4]

guile-2.2-libs/now 2.2.7+1-4 amd64 [installed,upgradable to: 2.2.7+1-6build2]

but nothing seems willing to to fix what do-release-upgrade wants to be fixed.

Is it safe to just use apt to remove guile-2.2-libs? If not, what do I do?

Why is Gstreamer in Ubuntu 26.04 on RPi5 not handling h.265 video (it was working in 24.04) https://askubuntu.com/questions/1566703/why-is-gstreamer-in-ubuntu-26-04-on-rpi5-not-handling-h-265-video-it-was-workin

My system is a Raspberry Pi 5 16GB running a fresh install of Ubuntu 26.04 with restricted extras installed plus all Gstreamer add-ons including good, bad and ugly.

If I use Showtime (Gstreamer-based) it cannot play videos encoded with h.265; the detailed error message is:

Error from element /GstPlayBin3:playbin3/GstURIDecodeBin3:uridecodebin3/GstDecodebin3:decodebin3-0/v4l2slh265dec:v4l2slh265dec1:   
Could not get/set settings from/on resource.  

Failed to configure the buffer pool

../gst-libs/gst/video/gstvideodecoder.c(4373): gst_video_decoder_decide_allocation_default (): /GstPlayBin3:playbin3/GstURIDecodeBin3:uridecodebin3/GstDecodebin3:decodebin3-0/v4l2slh265dec:v4l2slh265dec1:

Configuration is most likely invalid, please report this issue.

In other Gstreamer tests the error 'unsupported pixel format' is reported which is also h.265-related.

I can use other apps such as VLC to play h.265 videos, so that is not a problem, but because the [low-resource overhead] default file sharing on Ubuntu (simple on/off switch in settings menu) that I use to stream video to my TV (Rygel) is also Gstreamer-based, and because it cannot negotiate h.265 videos, it refuses to serve them. It also worked perfectly in 24.04 before I moved to 26.04.

I confirmed with a non-RPi5 user running Ubuntu 26.04 AMD64 build that Gstreamer works fine with h.265, and on the Raspberry Pi forum, a moderator said that Gstreamer fixes had recently been applied to RPiOS to address h.265 problems, so it could be that Ubuntu engineers have yet to get that across to the ARM-based Ubuntu 26.04 updates?

Wine does not see my GeForce GT 730 GPU properly anymore https://askubuntu.com/questions/1566696/wine-does-not-see-my-geforce-gt-730-gpu-properly-anymore

Wine 11.8 (both staging and dev) no longer sees my GeForce GT 730 GPU (a Fermi one) properly. Instead it reports 0 MB of memory and therefore all games and even dxdiag fail with "no memory":

I tried various workarounds, but none helped so far. Wine does not want to talk/respond to my GPU anymore. I'm not sure what happened. Instead it tries to use vulkan or other unsupported methods.

Alternative to GCPW for Ubuntu: How to link Google Workspace accounts to persistent local users? https://askubuntu.com/questions/1566668/alternative-to-gcpw-for-ubuntu-how-to-link-google-workspace-accounts-to-persist

I am looking for a Linux equivalent to GCPW (Google Credential Provider for Windows) for an Ubuntu deployment.

Our Current Workflow (on Windows): We use GCPW so employees can log into their laptops using their Google Workspace (Gmail) credentials. When a new employee joins, they select "Add Work Account" at the Windows login screen. After they authenticate with Google, the system automatically links that identity to a persistent local account/home directory on the machine.

What I am looking for in Ubuntu:

  1. A way for the user to authenticate via Google (ideally with a web-view for 2FA support) directly from the GDM login screen.

  2. Upon the first successful login, the system should automatically create a local user and home directory (e.g., /home/username) if it doesn't already exist.

  3. The account should remain on the laptop for offline use, similar to how a local account behaves.

How do I make F13 not open settings? https://askubuntu.com/questions/1566648/how-do-i-make-f13-not-open-settings

This is similar to How do I make F13 not open settings? (Ubuntu 24.04.2 LTS), but I'm in KDE now instead of GNOME, and I now have a physical F13 key on my keyboard. Every time I press it, Settings opens. This time, I don't really know what to try. How do I stop this nonsensical behaviour?

I'm trying to install packages on an offline PC using apt-offline, but I'm getting a 403 error on the online PC https://askubuntu.com/questions/1566635/im-trying-to-install-packages-on-an-offline-pc-using-apt-offline-but-im-getti

Offline PC: Ubuntu 24.04.4

sudo apt update (Online only at this point)
sudo apt install apt-offline_1.8.5-1_all.deb (Online only at this point)

Online PC: Ubuntu 24.04.4

sudo apt update
sudo apt install apt-offline

I tried to install various packages on the offline PC using apt-offline, following instructions I found online.

However, when I transfer the sig file generated on the offline PC to the online PC and try to download the packages as instructed, I get the same message for every package, and the download fails, creating a zip file with 0 bytes.

VERBOSE: http://archive.ubuntu.com/ubuntu/pool/main/m/mozc/mozc-data_2.28.4715.102%2bdfsg-2.2build7_all.deb - 403 - Forbidden

I can download the corresponding deb file by accessing this URL directly from my browser (Firefox) at online PC.

I don't understand why downloading with `apt-offline get *.sig --bundle *.zip` results in a 403 error, even though I can download it from the browser.

How can I obtain the zip file using apt-offline?

Both my offline and online PCs are mostly in their original Ubuntu 24.04.4 state, except for enabling the firewall.

I haven't touched any repository settings. The image used to install Ubuntu 24.04.4 was "ubuntu-24.04.4-desktop-amd64.iso," which was downloaded from the official Ubuntu website.

Both events are scheduled to take place around May 8, 2026.

The following are the details of the execution in the terminal on the offline PC.

It is solved. (May 13, 2026)

I want to install a package on an offline PC using apt-offline, but I'm getting a 403 error on the online PC.

The reason is apparently that "apt-offline uses Python-urllib/3.12 in the User-Agent header. However, Canonical seems to reject programs with this header." (Teacher: Andrei Borzenkov)

The workaround is as follows:

  1. On the offline PC, execute the following in the terminal with curl -LO before the download URL described in the sig file generated by apt-offline:

Example: 'https://..xxx_%2b[varsion].deb' 'xxx_%2b[varsion].deb' [deb file size] MD5sum:yyy Execute in the terminal with curl -LO before the first 'https://..xxx_%2b[varsion].deb' (If curl is not installed, run sudo apt install curl)

  1. If the downloaded deb file name is the same as the second example 'xxx_%2b[version].deb', then leave it as is. If it's different, rename it to match the second example.

  2. Once you have all the necessary deb files for the package, compress them into a zip file with the same filename as the sig file, but with the extension changed to .zip. Example: xxx.sig -> xxx.zip

  3. Transfer that zip file to the offline PC.

  4. On the offline PC, run sudo apt-offline install xxx.zip. If all the necessary deb files are synced, the deb files will be copied to /var/cache/apt/archives, and apt will recognize the existence of the deb files in that location.

  5. On the offline PC, run sudo apt install xxx. apt will then install using the deb files copied to /var/cache/apt/archives.

Tiny FONT in KDE sddm "maya" greeter https://askubuntu.com/questions/1566627/tiny-font-in-kde-sddm-maya-greeter

For KDE Plasma SDDM (all names intenionally given here to allow search hits)
The default greeter "maya" uses a tiny CONDENSED "Font" and cannot be set to anything else by normal means, e.g. in /etc/sddm/font.conf .

Now, this looks awful on anything with a slightly modern resolution.
So a change is "urgent"; how to do it?

This appears to be disregarding "highdpi" settings and the scaling referenced in many postings. Here we are at the FONT setting, disregarding SCALING.

Tiny image due to restrictions:

enter image description here




Needs detail for clarity; really?
The specifics;
ON Ubuntu 24.04 (Gnome),
with How to Change Default Desktop Environment done.

I'd expect the maya greeter to be present in the same state "everywhere".
Feel free to tell everyone where that isn't the case!
The result: Is that a quick-transform into a light KUbuntu?

RDP remote login connection to Ubuntu 26.04: black screen https://askubuntu.com/questions/1566604/rdp-remote-login-connection-to-ubuntu-26-04-black-screen

I am unsuccessful in establishing a RDP remote login connection to Ubuntu 26.04LTS.
I followed the instructions here. It is a fresh installation of Ubuntu.

As a client I use Remmina on 24.04. Authentication works, but the screen remains black, with no error. Please see screenshot. The top border of the screen shows some "colors" when looking at it exactly.

enter image description here

In contrast, RDP Remote Desktop sharing works. Connection from other client devices equally do not work.

P.S. I did some further testing today, using a Windows 11 machine to connect. In fact, the Windows RDP client connects and logs in successfully to the Ubuntu 26.04 machine. So it is likely to be Remmina having some issues here?!The Windows RDP client only gives a warning about encryption: enter image description here

Remmina logs as follows:

openssh-server post-installation script error (exit status 10) and SSH not working https://askubuntu.com/questions/1566463/openssh-server-post-installation-script-error-exit-status-10-and-ssh-not-worki

I’m encountering an issue where openssh-server fails during configuration, and SSH is currently not working on my system.

This error appears during package operations, even when I’m not explicitly trying to install openssh-server.

What happens

During apt/dpkg operations, I see:

Setting up openssh-server (1:9.6p1-3ubuntu13.16) ...
dpkg: error processing package openssh-server (--configure):
 installed openssh-server package post-installation script subprocess returned error exit status 10
Errors were encountered while processing:
 openssh-server

What I’ve tried

  1. Re-running configuration:
sudo dpkg --configure -a

Same error persists.


  1. Running the post-install script manually with debugging:
sudo bash -x /var/lib/dpkg/info/openssh-server.postinst configure

This didn’t produce any obvious error output, and the last line is `exec /usr/share/debconf/frontend /var/lib/dpkg/info/openssh-server.postinst configure which tells me that something to do with package configuration is failing.


  1. Regenerating SSH host keys:
sudo rm -f /etc/ssh/ssh_host_*
sudo ssh-keygen -A

Keys were generated successfully, but the issue remains.

  1. Restore ssh config:
sudo cp /usr/share/openssh/sshd_config /etc/ssh/sshd_config

Observations

  • SSH into this machine is not functioning.

  • The openssh-server package is broken.

  • The post-installation script consistently exits with status 10.


Research

I found that post-installation script failures can be caused by misconfiguration or missing files, but most solutions suggest reinstalling or purging the package. I haven’t found a clear explanation for exit status 10 specifically or how to resolve it without risking further issues.

Previously, I have used this sequence of commands to fix similar errors:

rm -rf /var/lib/dpkg/info/<packagename>* (in this case openssh*)

dpkg --configure -a

Fix package post-installation script subprocess returned error exit status 10 for libpaper1:amd64

Error reinstalling isc-dhcp-server "post installation script returned error exit status 255"

Like in the above posts, which has fixed the error temporarily, but probably messed up the dpkg package lists or something.

The issue keeps coming back, it's a different package or packages every time so it seems like an issue with dpkg or a corrupt filesystem.

Any ideas what is causing this issue, and how I can resolve it without reinstalling the system?

Update: I got ssh server working again, but still seeing the error on install/configure. getting closer. these are the commands that fixed it and my logic behind them

sudo cp /usr/share/openssh/sshd_config /etc/ssh/sshd_config

-- there was no sshd config until i copied it from here

--- then uncommented the host keys in that file, and generated them. made sshd user

grep -n "HostKey" /etc/ssh/sshd_config

2140 ls -l /etc/ssh/sshd_config.d

2141 sshd -T | grep hostkey

2142 sudo nano /etc/ssh/sshd_config

2143 sshd -t

2145 ls -l /etc/ssh/ssh_host_*

2146 namei -l /etc/ssh/ssh_host_rsa_key

2147 sudo ssh-keygen -lf /etc/ssh/ssh_host_rsa_key

2148 sshd -T | head -50

2149 lsattr /etc/ssh/ssh_host_rsa_key

2150 mount | grep " / "

2151 sudo rm -f /etc/ssh/ssh_host_*

2152 sudo ssh-keygen -A

2153 sudo ls -l /etc/ssh/ssh_host_*

2154 sudo /usr/sbin/sshd -t -f /etc/ssh/sshd_config

2155 getent passwd sshd

2156 id sshd

--- no sshd user??

2157 sudo adduser --system --no-create-home --group sshd

2158 getent passwd sshd

2159 sudo sshd -t -f /etc/ssh/sshd_config

Kernel 6.17 failing on Raspberry Pi 4? https://askubuntu.com/questions/1562527/kernel-6-17-failing-on-raspberry-pi-4

I just upgraded my Raspberry Pi 4 to the 25.10 release, and it won't boot kernel 6.17, only the 6.14 kernel from 25.04. When I log in, I get:

piboot-try:
New boot assets in /boot/firmware/new failed. Fallen back to known good
state. Use piboot-try --reset-new to re-test boot assets. If you are able
to determine the boot failure is due to a bug, please file an issue:
ubuntu-bug flash-kernel

uname -r says it's running kernel 6.14.0-1019-raspi.

I've followed the advice in the message, but it still uses 6.14. I've looked through various logs, but I don't see anything that says what the error might be.

How can I find out what's going wrong with 6.17, and ideally how can I get the new kernel booting?

Is there any Ubuntu program that does speech to text? https://askubuntu.com/questions/1524735/is-there-any-ubuntu-program-that-does-speech-to-text

I need something that can be installed by ubuntu. I don't know how to make my own source code program and that seems to be everything i can find online. I don't need something that uses a browser either. Please include a "sudo apt-get install" command in any answer, as anything else is far too complicated, especially since typing is a problem. I'm fine with installing the ppa for it if needed, as long as a command for that is given as well. I really need a cut and paste way to install something via terminal.

can't find directory and file created with ubuntu https://askubuntu.com/questions/1245859/cant-find-directory-and-file-created-with-ubuntu

So I downloaded ubunto to start working with command line. It seems ubuntu created a directory that it named my username in my desktop (as discovered via pwd). I since created a file called colors.txt file using nano just for some practice. Using the ls command confirmed I created colors.txt.

However, I cannot find a folder that is called my username, or the file called colors.text anywhere on my computer. Is this normal? Where could this directory and colors.txt be?

Intel Turbo Boost not working properly 18.04 https://askubuntu.com/questions/1077856/intel-turbo-boost-not-working-properly-18-04

I have an I7-8750H and currently have a dual boot machine with Win10 and Ubuntu 18.04 with the 4.18.8 kernel.

When I stress test all cores of the cpu in windows it reaches 3.9 GHz which is as it should, but when i stress test in Ubuntu, the cores only reach 2.5 GHz.

I have tried changing the scaling governor but doesn't change the outcome.

i7z says:

Socket [0] - [physical cores=6, logical cores=12, max online cores ever=6]
TURBO ENABLED on 6 Cores, Hyper Threading ON
Max Frequency without considering Turbo 2307.32 MHz (100.32 x [23])
Max TURBO Multiplier (if Enabled) with 1/2/3/4/5/6 Cores is  41x/41x/40x/40x/39x/39x
Any app on Ubuntu to open and/or convert HEIF pictures (.HEIC, High Efficiency Image File Format)? https://askubuntu.com/questions/958355/any-app-on-ubuntu-to-open-and-or-convert-heif-pictures-heic-high-efficiency-i

A certain cellphone maker has changed the default format of taking pictures to HEIF (.HEIC, High Efficiency Image File Format), without asking the users (although there is still the option to use jpeg/jpg).

Is there an app/program on Ubuntu that can open and/or convert HEIF-pictures and even let them be edited?

Is there any tool to convert pdf to ppt/odp slides in Linux/ Ubuntu offline? https://askubuntu.com/questions/797836/is-there-any-tool-to-convert-pdf-to-ppt-odp-slides-in-linux-ubuntu-offline

I am looking for a tool that converts PDF into PPT files or supports any tweak to import PDF files into LibreOffice-impress, LibreOffice-Draw imports the PDF but that does not do the job. So far I am trying to use a workaround called pdftk+pdfchain to burst the pages of the PDF file into single page PDF files and then converting the single page PDF files into images using ImageMagic and importing them into a PPT slide.

Logitech USB headset not working in 14.04 https://askubuntu.com/questions/615599/logitech-usb-headset-not-working-in-14-04

I recently converted my laptop to Ubuntu 14.04 (two days ago at the time of this posting) and just encountered this problem (an hour or so ago at the time of this posting). The problem is that my Logitech headset is no longer working, but in the weirdest way possible. The sound control tab in the system settings shows the headset as the selected audio device but all the sound is played through the onboard speakers of my acer aspire 4743. all of the other functions of the headset remain the same (microphone and volume controls.). I have already messed around with alsamixer and tried the suggestions of other users but nothing has worked so far, any ideas? I am totally new to Linux and have no idea what might be causing this. Thanks, Eric

What is the difference between the core, full, extras and light packages for nginx? https://askubuntu.com/questions/553937/what-is-the-difference-between-the-core-full-extras-and-light-packages-for-ngi

nginx on Ubuntu is a virtual package provided by one of five packages from the official repositories (at least as of 14.04, defaulting to nginx-core, I believe):

$ apt-cache depends nginx | tail -n+2 | cut -d: -f 2 | sort -u
 nginx-core
 nginx-extras
 nginx-full
 nginx-light
 nginx-naxsi

What is the difference between these packages and what are the recommended use cases for them?

This somewhat old Debian Wiki page has a feature comparison between extras, full, light and naxsi, but no mention is made of core. How much of it has changed in 14.04?


secondary As I understand it, nginx doesn't support runtime enabling of modules like Apache does, so would installing nginx-extras impact performance?
