I have a question regarding installing Linux on ASUS laptops with OLED displays. Is it safe to use Linux on OLED-equipped ASUS laptops in the long term?

The reason I’m asking is that on Windows, the MyASUS application provides a feature called Pixel Refresh, which is designed to help prevent pixel burn-in on OLED panels. As far as I know, this feature runs at the software/firmware level and is easily accessible in Windows, however on Linux there is no MyASUS app, and therefore no obvious way to manually trigger or manage Pixel Refresh.

My questions are:

• Does Pixel Refresh work automatically at the firmware/hardware level even when using Linux?

• Is there any official recommendation from ASUS regarding OLED care when running Linux?

• Are Linux users at a higher risk of burn-in due to the lack of MyASUS features?

I’d really appreciate insights from ASUS staff or users who have been running Linux on OLED ASUS laptops for a long time.

How is the boot options menu generated? I have one version of Xubuntu and nothing else on my machine, yet the menu lists a dozen items.

The first 4 menu items are:

UEFI OS
ubuntu (P0: ST1000DM003-1CH162)
UEFI: ST1000DM0003-1CH162
ubuntu

...

These are repeated randomly down the list. Where is this stored or how is it generated? How do I get rid of the unnecessary repetitions? Some of the options when selected for boot work fine. Others just bring up a grub> prompt. What is this? I have a lot of questions I'm afraid, but that's what 8 days trying to get this working does!

I'm running Ubuntu 24.04.3 LTS. How to stop Chrome from asking for keyring password the first time I open Chrome? I know this can be switched off, but things have changed since the last time I had to do this.

i was using windows 10 before then changed to ubuntu. after i open a folder from ide. im seeing

Unable to access location
Error mounting/dev/sdb4 at/media/acc/Others1: wrong fs type, bad option, bad superblock on/dev/sdb4, missing codepage or helper program, or other error

i tried to fix it with

sudo umount /mnt/Others
sudo ntfsfix /dev/sdb4
sudo mkdir -p /media/acc/Others
sudo mount -t ntfs-3g /dev/sdb4 /media/acc/Others
sudo systemctl daemon-reload

but its temporary, after reboot i need do it again.

For the past several weeks, my normally stable Kubuntu 24.04.3 system will randomly freeze (only the cursor will move, but does nothing) . At other times the display turns completely black. In both of these cases, I have to force a shutdown. Video thumbnails do not display correctly: they are colored lines - see screenshot at bottom. Attempting to view a page (Firefox 147.0.1) with embedded videos will cause freezing or black screens about 50% of the time.

I have 2 of these systems, and they both exhibit this unruly behavior.

Error messages from the last forced shutdown - I think the radeon errors are the most significant (?) as they occurred just before the shutdown:

The last kernel update, as far as I can tell, was 12-12-2025. This was approximately when these problems started, but I am not sure of that.

I ran memtest86 for 30 hours on my 32GB of RAM with no problems detected. I keep both systems updated and have not installed any new hardware or software (other than Linux updates). Behavior may be related to this bug (seems similar)? https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/2063983 I am unsure how to proceed.

The screenshot below is how some (but not all) video thumbnails are rendered.

After a recent Ubuntu update, Bluetooth audio on a Sony WH‑1000XM4 headset no longer works in High Fidelity (A2DP sink Codec SBC) mode, including SBC‑XQ and AAC. The headset connects successfully and appears to negotiate the A2DP profile, but audio playback fails immediately. Sound still works in HSP/HFP (Headset/Handset mode).

The failure occurs at the moment PipeWire/WirePlumber attempts to start the A2DP audio stream. The Bluetooth transport opens, then instantly closes with an error.

Notes

• I restarted pulse, bluetooth, and everything I could think of
• I restarted the machine after setting changes
• I added this to ~/.config/pipewire/media-session.d/bluez-monitor.conf

   properties = {
     bluez5.codecs = [ sbc sbc_xq ]
     bluez5.default.rate = 48000
     bluez5.default.channels = 2
     bluez5.sbc-xq.bitpool = 76
   }

No effect

At this point I am not sure what else to try . The headset was working fine for years before this problem

I am moving my Windows Notepad++ python scripts to my Ubuntu 24 machine that has NP++ snap (under Wine).

It looks like I can't simply dump the scripts into the script folder under NP++ on Linux. Snaps seem ... closed off.

Is there a way to bulk add files (here, Python scripts) to a NP++ installation?

I can use a console import instruction to an external folder and import that way, but that would be messy! Scripts in the NP++ folder can be run directly without going through the console.

I've noticed that sometimes one of my terminal windows will start acting weirdly when I change focus to a different window, and then click inside the terminal window to bring focus back to it. For example, if I'm entering a password, I often switch over to my password manager to copy the password, and then switch back to paste it. When the Terminal window is in this state, the password will fail the first time (after the focus change), but then succeed the second time.

I used getpass() in a Python interactive session to detect what's going on, and it looks like the focus change is triggering a couple of control sequences. I clicked out of the window when the Password: prompt came up, and then clicked back, and typed "asdf" as the password:

>>> print(repr(getpass.getpass()))
Password: 
'\x1b[O\x1b[Iasdf'

What is causing this, and how do I disable it (other than closing the Terminal window and opening a new one)?

EDIT: I'm using the default terminal in Ubuntu 20.04. I tagged this question with gnome-terminal, but I'm not 100% sure that's right.

The question is, if the same package could be installed in mac why does it give an error in Ubuntu?

I've had this machine for years and it has 22.04.1 on it; URLs to the local filesystem via file:/// no longer work except those in my home directory, everything else gives a File not found.

How do I get my local filesystem access back so I can check HTML edits in a browser before uploading?

I should add I spent a long time this morning trying to solve this, screwing around with user profiles and other stuff I found online while looking for a solution, but nothing worked, so here I am.

I need to auto run the python script (having some print statements) in Ubuntu upon every restart. I have typed crontab -e that opens a file in nano. I just have written the following line at the end of the file and save it.

When I reboot the virtual machine, I don't see any print statements on the terminal or on the screen.

Any idea what could be the problem.

I am hitting a wall trying to configure a dual GPU setup on a B550/Ryzen platform running Ubuntu. I am facing a persistent Memory Mapped I/O (MMIO) resource allocation issue where the kernel cannot assign BAR addresses for the second GPU, leading to can't assign; no space errors.

Hardware Specs:

• CPU: AMD Ryzen 7 5800X

• Mobo: B550 Chipset [INSERT YOUR MOTHERBOARD MODEL HERE]

• GPU 1: NVIDIA RTX 4060

• GPU 2: NVIDIA RTX 5060 (New gen)

• PSU: 850W

• OS: Ubuntu (Kernel 6.x generic)

• Driver: Manual install of NVIDIA-Linux-x86_64-580.126.09.run (Required for 5060 support)

The Problem: When booting with default BIOS settings, only one GPU is enumerated correctly. The second GPU fails with BAR allocation errors in dmesg. When I attempt to fix this by enabling "Above 4G Decoding" in BIOS, the system fails to mount the NVMe drive or panics during boot unless I use specific kernel parameters, and even then, I lose the proprietary driver binding.

Logs & Symptoms:

1. The BAR Error (dmesg output): Without 4G decoding, the kernel clearly sees the device but cannot map the memory:

Bash

[ 0.666193] pci 0000:07:00.0: BAR 1 [mem size 0x10000000 64bit pref]: can't assign; no space
[ 0.666195] pci 0000:07:00.0: BAR 1 [mem size 0x10000000 64bit pref]: failed to assign
[ 0.666196] pci 0000:07:00.0: VF BAR 2 [mem size 0x10000000 64bit pref]: can't assign; no space
NVRM: BAR1 is 0M @ 0x0 (PCI:0000:04:00.0)

2. The IOMMU/Disk Conflict: If I Enable Above 4G Decoding and Disable CSM (UEFI only), the boot process hangs with filesystem errors, losing access to the NVMe block devices:

Bash

/var/lib/snapd/snaps/firefox_2356.snap: Can't lookup blockdev
[FAILED] Failed to mount Mount unit for firefox.
[FAILED] Failed to mount Mount unit for snapd.

What I have tried so far:

1. BIOS Settings:

   • Above 4G Decoding: Enabled

   • Re-Size BAR: Auto/Enabled

   • CSM: Disabled

2. Kernel Parameters:

   • Tried pci=realloc: Did not resolve the no space error.

   • Tried iommu=soft: This allows the system to boot with "Above 4G Decoding" enabled (bypassing the blockdev error), BUT nvidia-smi fails to detect devices, or the system falls back to llvmpipe (software rendering) with a zoomed-in resolution.

3. Display Manager:

   • Disabled Wayland in /etc/gdm3/custom.conf (WaylandEnable=false).

4. Driver Installation:

   • Purged all apt nvidia packages.

   • Running the .run file for driver 580.126.09.

   • Installation completes successfully in Recovery Mode (Root Shell), but upon rebooting with iommu=soft, the driver doesn't seem to bind correctly to the cards.

The Question: How can I properly expose the BAR address space for both cards on a B550/Ryzen platform without breaking the NVMe/IOMMU controller? Is there a specific combination of GRUB parameters (e.g., pci=noalloc, iommu=pt, amd_iommu=on) that allows 4G decoding to coexist with a functional NVIDIA driver on this chipset?

Any insights on how to escape this loop would be appreciated.

Issue description:

I'm running Ubuntu with a dual monitor (desktop integrated display + external monitor) for months. Both monitors are independent (joint display as opposed to clone mode). Since the beginning of this week, the integrated display randomly freezes. Even the mouse cursor remains displayed on the frozen screen. Meanwhile, the Ubuntu system and the external monitor keep working normally. The external monitor is configured as the main desktop display. Thus, I can open the settings. Then, switching to clone mode and immediately back to joint mode revive the integrated display.

I'm wondering if a recent software update may have compromised the system stability. Also, I noticed the computer may sometime be very busy, fans are running fast, during power saving mode. In this case, I'm unable to wake up the computer (forced power down).

Could you please help me diagnose the reasons why this occurs and, maybe, find a fix?

I installed slack via sudo snap install slack which returned

slack 4.43.49 from Slack✓ installed

but when I run slack I get the error

The issue become apparent after I didn't eject my USB drive before I removed/unplugged my USB drive.

What happened with my drive? Is it already broken? Is there any way to fix this?

My overall goal is to have nodes of a cluster PXE boot and connect to a docker swarm located on the control node. Right now, im following the instructions shown here: https://manski.net/2016/09/pxe-server-on-existing-network-dhcp-proxy-on-ubuntu/. How can I get passed the error shown above? Is there an easier way to do this?

Edit: I'm using Ubuntu Desktop 20.04 on the control node, and all other nodes are set to PXE boot.

I have a Dell Inspiron 1525 laptop and I get no sound from it. In Sound settings I have only an HDMI option. Here is the output of play -l:

Ι also used this command with no result:

I tried removing/reinstalling the ALSA packages. After that, my headphones are working, only the speakers of the laptop do not work.

Please help me, as this is the 4th time I try to install Ubuntu with the same result.

I want to completely get rid of Microsoft (thus Windows), and I really love the Ubuntu operating system and applications. I had Ubuntu installed before on my computer, and it worked perfectly. For some reason I switched back to Windows, but now I want to completely get rid of Windows, but I can't.

I've installed Ubuntu several times on mine and others' PCs. It has always worked, but now I'm stuck at the very unclear message Couldn't get size.

I get a black screen with the following boot messages when trying to boot the Ubuntu installer using nomodeset:

I've searched on this and other forums, and I've found a couple of solutions including:

• Using nomodeset & nouveau.modeset=0 (See screenshot)
• Using no splash
• Using CSM in UEFI setup
• Using Secure Boot either enabled or disabled in UEFI (I tried both)
• Using Safe Graphics when booting from GRUB
• Using the motherboard graphics instead of the GPU graphics by plugging in the HDMI cable directly to the motherboard

Actually nothing worked. I keep getting Couldn't get size, and when I remove quiet splash or use no splash, I see Registered PHC Clock. I know this isn't an error, but it hangs on that one and doesn't continue booting (even after 30 minutes).

I don't think it's caused by the GPU, because it also doesn't work with the motherboard graphics.

I hope someone has a brilliant idea which makes my system at least boot into the Ubuntu installer and desktop where I can fix some of these issues.

I have an Edimax external USB network adapter which is not recognized after I plug it into my Ubuntu 18.04 laptop. First of all I ask Ubuntu to list me all USB devices by lsusb. It shows all connected devices (and even more, this laptop has only two USB ports, but lsusb prints 5 records. Why is that?) beside that network adapter. When I unplug it and plug it in again dmesg also doesn't mention it at all.

The adapter itself works properly on another laptop with Windows. The USB port is also OK since other devices work OK, so what is the problem?

At work I have the exact same adapter (in terms of model and manufacturer) and that one works OK.

I'm trying to install Ubuntu 18.04 on a Dell XPS9560 with an Intel Core i7-7700HQ and It was freezing up on the splash screen. I started it again and disabled the splash screen in the GRUB command line and I saw it freeze with these repeated "soft lockups" on several different processes. I'm pretty sure it's not a low-level hardware failure because I have Ubuntu 16.04 and Kubuntu 18.04 installed on two different partitions of this computer and both work fine.

Do you have any idea what could cause this?

Does anyone have an Idea what to do next? Do I have to buy a new mainboard?

Thanks for helping!!

I had a Windows 10 and Ubuntu 16.04 dual boot on my laptop. I used both OSs for more than a year. Then my Windows OS was attacked by a harmful virus. After that I formatted the Windows partition (C:/) then booted Windows 10 again. Now my Ubuntu partition is missing. When I check with Windows Disk Manager my Ubuntu partition shows as free space (Not unallocated). I tried Ubuntu again with a CD, but the partition was not showing up there. I didn't back up my Ubuntu partition before this.

How can I recover my data back from my Ubuntu partition and dual boot both OSs again?

GParted:

I recently tried to install Ubuntu on my desktop and suprisingly I failed. I was trying Ubuntu and Ubuntu GNOME, both versions 16.04.2 and also the newest stable Linux Mint (LTS version). Bootable USB were made using Universal USB Installer.

All bootable USBs started Live systems without problems. I chose secondary HDD /dev/sdb and I created three partitions, assigning:

• 16GB for root
• 8GB for swap (I've got 32GB RAM)
• the rest of free space (about 100GB) for home.

The problems started after installation on local HDD.

Mint is separate story, because I didn't even see GRUB, it just booted to grub rescue mode, scaring me as hell, because I couldn't boot Windows. Anyway, booting Mint Live USB and running Boot-Repair finally allowed me to boot Mint from HDD. But I wanted to try with Ubuntu (yeah, I know Mint comes more or less from Ubuntu).
Ubuntus are more interesting.

After setup, first run showed grub and when Ubuntu was chosen, system ended up like this CLICK (photo made after starting Ubuntu recovery mode, or something like that, I don't remember the exact name)

For Google indexing purposes I'll quote:

Gave up waiting for root device
(...)
ALERT! UUID=<correct uuid here> does not exist. Dropping to a shell!

And the BusyBox (initramfs) prompt shows up, but keyboard is not responding (USB keyboard with wire).

I am not a Linux guru, so I started googling and trying thing one by one. I found this problem quite common, but I failed to fix it using common solutions. Things I've tried:

• Boot Repair
• adding rootdelay to grub commandline
• mounting root from Live USB and then grub-install and update-grub
• e2fsck

Nothing. Literally no change. What should I try now?

I am running 12.04.5 LTS on linux 3.13.0-65-generic kernel

When I run dpkg-reconfigure -a, it gives me the following:

Package `flashplugin-nonfree-extrasound' is not installed and no info is available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
/usr/sbin/dpkg-reconfigure: flashplugin-nonfree-extrasound is not installed

I purged and reinstalled the package using apt-get, and there's no change.

Also, when I run sudo dpkg-reconfigure $(dpkg -l | awk '{print $2}' | grep "^xserver" | tr '\n' ' '), I get:

/usr/sbin/dpkg-reconfigure: xserver-common-lts-trusty is broken or not fully installed

When I run sudo dpkg-reconfigure $(dpkg -l | awk '{print $2}' | grep 'lts-raring' | tr '\n' ' ') I get:

/usr/sbin/dpkg-reconfigure: libgl1-mesa-dri-lts-raring:i386 is broken or not fully installed

How should I fix it?

I've done all the autoclean and autoremove stuff, and they don't give any errors. But it seems I have some serious broken package issues.

I am using Ubuntu 14.04. I want to use Multicharts, a Windows application using Wine. Multicharts requires .NET Framework 3.5. Is it possible to install it? I have a 64-bit OS. I found the below code at a different question.

winetricks dotnet30

There appears to be a problem with the OS being 64-bit.

I was using xrdp to remotely connect from my Windows laptop to Ubuntu server. It was doing OK, but it failed all out of sudden after a weekend. I did a >#service xrdp status and it returned:

* Checking status of Remote Desktop Protocol server xrdp                [ OK ]  
* Checking status of RDP Session Manager sesman                         [Fail] 

WiFi hotspot not working with windows phone 8 and of course its not working with a any other phones as well. I have tried both Android and Windows phone 8. Either of these devices doesn't even detect Ubuntu's hotspot as I have tried many possible ways..

I'm in a corporate environment with a DHCP server with static assignments for my server. I have one physical nic with several sub-interfaces. I statically assign different MAC addresses for each sub-interface to get another IP address from the DHCP server. For some reason, my server is not taking the static MAC addresses. You'll notice that ifconfig shows each interface with the same MAC.

How do I assign unique MAC addresses to my sub-interfaces?

$ cat interfaces

auto lo 
iface lo inet loopback

auto eth0:1
iface eth0:1 inet dhcp 
        hwaddress ether 00:0c:29:31:24:fa
        hostname gwrt-test
        client gwrt-test

auto eth0:2
iface eth0:2 inet dhcp
        hwaddress ether 00:0c:29:31:25:fa
        hostname gwrt-test2
        client gwrt-test2

$ ifconfig

I have an old Dell Inspiron 1525, which had only Ubuntu 13.04 installed on it previously. For reasons not relevant to this post, I had to reinstall the Windows Vista that originally came with this laptop. For installing Windows, I moved the Ubuntu installation to a logical partition.

Before installing Windows, I had verified booting Ubuntu 13.04 from the new partition, but after installing Windows Vista, the Ubuntu partition is showing as unallocated. I have other partitions (all ext4) and they are all intact. I have checked the partition layout with GParted and also Windows Disk Management. It's only the Ubuntu partition that is showing up as unallocated/free.

Is it possible to recover this Ubuntu partition, and if yes, what are the steps?
