i am using cacti server Version 0.8.8a with SQL base (not mariadb). Now i installed new cacti version with "marijadb". Is it possible to move all data to new version which are configured at old version 0.8.8a ?
I'm not sure what data needs to be transferred. I think it's the sql database and rrd files?
I have Ubuntu Questing on a server I connect to with xrdp. When I switch to KDE Plasma from XFCE4, the size of the display is smaller than normal, and doesn't fit the whole screen. I tried scaling, but that is like a zoom. How can I configure KDE-Plasma to use the whole size of the display?
I want to add multiple locations in Typhoon weather app. A recent version of the app featured support for multiple locations.
How to enable multiple locations in Typhoon?
I am using a laptop (dell) connected to a docking station (no USB-C ports available) with two external monitors connected through a KVM switch using DVI cables. Both monitors are identical in model and brand (HP). However, Ubuntu 25.10 only detects one of the two monitors. Previously (24.10), Ubuntu was able to recognize both screens without issues.
Window is not presant on the laptop.
However, when I connect the same monitors to a desktop running Ubuntu 25.10 (using the terminal), both monitors work fine.
Additionally, from time to time, the laptop screen or the external monitors display a cloud of black and white dots (static noise).
What steps can I take to troubleshoot and restore detection of the second monitor? Are there specific configurations, driver updates, or commands I should try?
The hardware is old. There is no

I have updated the OS of this laptop to Ubuntu 24.04. Initially none of the drivers for WiFi and Bluetooth were detected, so I rectified these issues, but now the microphone is not working on this system. I have tried all of the potential fixes provided by ChatGPT and Claude, but none of them worked.
My microSD card will not mount in the built-in SD card reader or in a USB adapter. It worked fine earlier in the adapter, then I ate dinner, came back, and now it plays the noise when I plug it in, but it doesn't show up in Files. It does show up in Disks, but it will not let me mount it. There's no play button, and all of the options are grayed out in the dropdown menu.
Another USB drive is working fine.
I have a fresh install of Ubuntu 22.04.5. All updates are applied. The updates did fix the initial no WiFi issue. All the other hardware seems to work. External HDMI has not been not tested.
Changing color profiles has no effect. That includes the test: Swap red and green profile.
Switching between Wayland and X11 has no effect.
Doing a list of available drivers gives no results, but it does appear to be a driver issue. Current driver Tigerlake-LP GT2 [Iris Xe Graphics] (Rev 01) -- modules: i915, xe. Is there a driver configuration file?
This appears to be an old problem, but none of the found fixes have had any results.
I've been trying to install a plugin for my HP LaserJet M140we to get the scanner to work on my Cinnamon, but I have run into the issue of Python gobject/dbus is not being allowed to be installed without any further prompting. I am uncertain how to proceed as I would love to be able to scan documents (drawings, pamphlets, handouts, recipes, etc.) into my computer.
Is there currently a workaround? I don't have a custom Python to my knowledge, as I had requested a store to install Cinnamon for me. (I had somehow trashed two prior thumb drives and wasn't going to waste another $10 to do so again.)

It seems to be the script I got when looking up my OS fully. The system only gives the "pretty name" it seems.
Launching the HP device manager for Ubuntu after its installation works perfectly and the printer works. It seems to add functionality to my printer and requires it to install a plugin specifically for it.
I do all the steps required to install the plugin (Click Scan, Next when prompted for plugin installation, choosing either the downloaded plugin or searching from the internet). When it asks for the Admin password, it fails citing that reason stated in the title, but only in the terminal. It's also the recommended path, and I'm not sure what is wrong or not working.
I just got a bare bone pc(um880) that I installed linux on. I did not back it up,and it got corrupted! My root is stuck in lvm/vgmint-root, I think thd rest of files are on hd0, gpt2. The linux line says

We are facing a critical storage issue on an Ubuntu Server running on bare metal hardware, and we need guidance on safe recovery steps.
System details:
lsblk, /proc/partitions, or sysfs). As a result, the LVM Volume Group is in a degraded state with one missing Physical Volume.Current LVM state (summary):
Observed behavior:
Actions already taken:
Writes have been stopped.
Filesystem has been remounted read-only.
Critical data is being copied off the system.
No destructive LVM commands (vgreduce, pvremove, fsck) have been executed.
We would like confirmation and guidance on:
Whether Ubuntu provides any safe, supported method to stabilize or recover an LVM VG when a PV is permanently missing (without RAID/mirroring)
Best practice steps to avoid further data corruption while the LV remains active
Confirmation that data recovery is limited to copying readable data off the mounted filesystem before shutdown.
Please note this is a high impact production issue, and data integrity is the top priority.
The HDD is Internal. We still have not removed disk.

Using azerty, this should change the app to the second one in the dock, however with Wayland this types "é" in the opened window. Other [Super]+[num] shortcuts work well. For example [Super]+& opens the first app. The shortcut works well using Xorg. It seems to be a known issue, but I found no easy solution.
EDIT: additional information:
gsettings get org.gnome.shell.keybindings switch-to-application-2 returns: ['<Super>2']Till Ubuntu 22.04 I could just replace the /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.ogg with a new sound file (with the same name) and it worked.
But in Ubuntu 24.04 it does not work. The same beeping sound reappears although I even deleted the file (/usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga – oga instead of ogg in the past).
Is there a new place and folder?
(I searched the internet and dconf-editor but could not find any hint for a new location or solution.)
On a fresh install of Ubuntu 24.04 Desktop on an old Dell Precision T3600, I'm experiencing constant mouse and keyboard freezes that require a reboot to recover. I've also tried to install 24.04 on a virtual machine on an XCP-ng 8.2.1 host but cannot even complete the install process without having to reboot the VM and rebuild it.
I've never had this kind of problems with an Ubuntu long term release going back to the original one in June 2006 or any previous release going back to the original one in 2004.
Has anyone else had the mouse / keyboard freeze problem and, if so, were you able to resolve the issue and how? As it is ... this new long term release is completely unusable.
So my monitor stopped working,
when I was messing around with the the rotation
(ie xrander -o [ normal, left, right, inverted ] stuff).
(
The monitor input is DVI (DVI-D Dual Link),
and the laptop's output port is HDMI,
so they're connected with an adapter.
)
All (I think) of the relevant dmesg output:

I did test it with a live-USB distro where the monitor was working before
(to make sure it wasn't just some messed up configuration in my kde plasma desktop environment or whatever),
but it doesn't work there either.
And after googling a bit,
it seems that apparently this is an actual known problem?
Like, the actual data in the EEPROM memory chip in a monitor itself can get corrupted while plugging the monitor in and out and stuff?
(Well, I'm personally pretty surprised and confused to learn that.)
But apparently that data,
the monitor just gives it to the computer,
so that the computer knows what different settings the monitor can do (in terms of resolution/refresh-rate/etc),
and then the computer uses it to decide what signal it sends to the monitor and how
-- but I'm not sure whether the monitor plays any further active role at that point,
or just "passively" displays whatever signal it receives from the computer...?
(
ie, I'm not sure
(assuming I can get a file with a non-corrupt EDID for the monitor)
whether:
(1) I would need to actually write that data back onto the chip in the monitor somehow(?)
(2) or if I could just tell the operating system like:
"I know the EDID data you're getting from the monitor is wrong, so use this file instead"
... ?
)
Also, I don't know how I can get a file with a non-corrupt EDID for the monitor?
Like, it's a "Samsung SyncMaster B2030",
and I was able to google up copies of EDID files for other monitors,
but not for this specific model...?
(I did find a .exe file for the Windows drivers (I think), so could I maybe extract the data from that somehow??)
it is a minor "problem" but I don't understand why I don't have quiet boot on despite having the option GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" in the /etc/default/grub file (which was by default. I haven't edited anything).
To be more clear this is what I see.
Isn't that what should happen without the quiet option?
The output of cat /proc/cmdline is this:
BOOT_IMAGE=/boot/vmlinuz-6.0.9-060009-generic

I have been experiencing extremely slow bootup on Ubuntu 20.04. I have Lenovo Thinkpad X201. The boot does not take that long for another Ubuntu 18.04 that I have installed on another partition.
Running dmesg in terminal and reading the output shows following lines that are probably related to delaying of boot :

This is what I've done so far on a fresh Ububntu 20.04 installation:
wget https://dev.mysql.com/get/mysql-apt-config_0.8.12-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.12-1_all.deb
In the prompt, I chose Ubuntu Bionic.
In the next prompt, I selected MySQL 5.7 server.
The next prompt selects MySQL5.7 by default. I chose the last option Ok.
sudo apt-get update
sudo apt-cache policy mysql-server

So what can I do ?
Can someone help me ?
Before installing Ubuntu 19.10 on my 64GB USB2.0 flash drive i did some research on partition schemes. Most of the websites recommended 2GB-8GB for the root (/) partition.
But,to play on the safe side i set it to 10GB.
and guess what happened 1 week later.
I get notified that only 1GB of root space is left !!!
I freaked out and changed the size of the partition a few hours back AND.IT.RUINED.THE.PERFORMANCE !!!
I had this configuration when i installed Ubuntu.
root = 10GB
swap = 2GB
home ~ 50GB
and now, what I did is:
root = 32GB
swap = 2GB
home ~ 28GB
I was expecting better performance But what followed totally pissed me off.
*Now the OS boots in about 1.5 minutes!
Please let me know how i can make the boot process faster !
I just remembered that before I changed the partitions I was having a problem with the CD drive popping out. SoI opened it up, removed the ribbon cable (or whatever that's called), taped it and left it inside. So my CD drive does not pop out every 20 seconds. Do you think it has any impact on the performance?
Please let me know what to do in this case.
Were those websites I followed wrong, Or I make some mistake in the first place?

When I use a live USB for Ubuntu 18.04 LTS (or other Debian distros actually), depending on what options I choose in grub, I get stuck on either a screen tearing, looking like this:
or stuck at a message saying:
BIOS contains WGDS but no WRDS
Just the default "live mode" results in a screen tearing like in the screenshot.
I have a GTX 1660
System Model ROG Strix GL10CS_GL10CS
I disabled Secure Boot in the BIOS also.
I tried various USB drives and ISOs, but it's still the same.
What else could I try to fix this?
The OOM Killer or Out Of Memory Killer is a process that the linux kernel employs when the system is critically low on memory. ... This maximises the use of system memory by ensuring that the memory that is allocated to processes is being actively used.

A quicker method than the 1/2 hour it takes in the self-answer would be accepted.

"bind:bind" works but I couldn't follow that. Is that a reference to the directory being owned by a user named "bind" and belonging to the "bind" group? I would have commented on that question asking for more info but at least 50 reputation is required.
I noticed this in syslog:
Jul 6 22:30:52 mail kernel: [1835655.620976] audit: type=1400 audit(1562409052.847:297): apparmor="DENIED" operation="open" profile="/usr/sbin/named" name="/var/log/bind/bind.log" pid=10582 comm="isc-worker0000" requested_mask="ac" denied_mask="ac" fsuid=120 ouid=0
I just made a switch from Windows to Ubuntu. The only problem is that it takes 4-5 minutes, sometimes up to 7 minutes to boot. This is rather annoying.
I ran the command systemd-analyze and it shows the following.
$ systemd-analyze

Lenovo Yoga 910 USB-C port is not working with Ubuntu 18.04.
kern.log doesn't output anything when I plug something in.
When I put the same hub to USB-C port that is meant to charge the battery it works. So I guess that that port is just disabled and I need to wake it up somehow. Because before reinstalling Ubuntu it was working just fine. Maybe I need some extra software (drivers) to fix that?

$ hdfs namenode -format
Yet the terminal answered me :

So I did :
mike@mike-thinks:~$ sudo chown -R mike /usr/local/hadoop
But even with it I still get :
mike@mike-thinks:~$ sudo hdfs namenode -format
sudo: hdfs: command not found
I have Ubuntu 14.04.5 LTS running on a HP microserver, no desktop or GUI.
I have installed GParted Live on a USB drive and booted to it. My plan was to reduce the size of /dev/sda2 by about 750MB, then increase /boot by that same amount. The problem is I can only reduce /dev/sda2 by about 3 MB, and I can't even increase /dev/sda1 by that.
Is this possible or do I need to repartition the drive and reinstall Ubuntu?

This is a new system. I have just installed Windows 10 and drivers. There's still no data on the SSD. I need to shrink Partition C: to be 50GB so I can create 3 other partitions (Data + Ubuntu + swap). Windows 10 Disk Management doesn't allow me to shrink the partition to less than ~240GB.
How to safely shrink these partitions?
I have a Acer Aspire 5741G and I installed Ubuntu 16.04 LTS recently. I have windows 7 pro as the other OS (dual boot). I get really slow boot times. It takes roughly 2 minutes to show all the icons on my desktop.
When I try running systemd-analyze , it shows around a minute mostly (screenshot attached). Screenshot for systemd-analyze blame also attached. Can the boot time be possibly reduced? Also, my screen flashes few times before the purple loading screen while booting. After some searches, people said it has something to do with the graphic card. Can I make this right?

I'm looking for a command line software/script for linux/ubuntu that can help me convert svg or ttf to otf, eot and woff formats.
I've tried fontmin,webify, fontforge, eot-utils, sfnt2woff, ttf2woff and other alternative as much as i can, I can't find a good converter.
fontmin convert files to ttf otf but doesn't convert to woff and is always broken. fontforge doesn't convert to woff and eot either, sfnt2woff and ttf2woff only convert to woff.
I'm simply trying to make web fonts css after converting process, I've also tried many alternative for it but so far no success at all.
Please let me know if there are batter option to accomplish my requirements. and feel free to edit and correct my question.
Is there any weather app that works with Ubuntu 12.04?
I tried many of them including the screenlets.
Nothing seems to work.
