Anyone else having issues with Nvidia drivers on updating to the latest kernel on Ubuntu 26.04?

Apt install log:

Error! Bad return status for module build on kernel: 7.0.0-42-generic (x86_64)
Consult /var/lib/dkms/nvidia/615.71.10/build/make.log for more information.
Builds for the following kernel(s) failed: 7.0.0-42-generic
dpkg: error processing package nvidia-dkms-open (--configure):
old nvidia-dkms-open package postinst maintainer script subprocess failed with exit status 10
dpkg: dependency problems prevent configuration of nvidia-driver-open:
nvidia-driver-open depends on nvidia-dkms-open (= 615.71.10-1ubuntu1); however:
Package nvidia-dkms-open is not configured yet.

Looking in that make.log a bunch of compile errors like:

././common/inc/nv-linux.h:1270:34: error: field <E2><80><98>cxlds<E2><80><99> has incomplete type
1270 | struct cxl_dev_state cxlds;
| ^~~~~

Seems to build fine for my backup (?) kernel 7.0.0-38-generic

I recently switched from Mint to Ubuntu, and the overall experience has been great aside from a few issues. I use Code::Blocks for C++ programming.

First, when I installed it via the App Center, the system couldn't find or launch it, even though the App Center showed it as installed. I eventually fixed this by manually installing it via sudo apt install codeblocks, so it seems like there might be an issue with how the App Center handles that package.

Second, since Ubuntu now uses Ptyxis as the default terminal, I'm running into an issue with C++ console outputs. Code::Blocks' settings only list older options like gnome-terminal and don't include Ptyxis out of the box. Could anyone help me figure out how to configure Code::Blocks to use Ptyxis for C++ outputs?

Hey!

Simple question - How does Ubuntu compare to other distros like Cachy, Omarchy, Fedora?

Like everyone is pushing gaming, ai development and so on and everyone hates Ubuntu.

These days I am got in a battle between rolling release distros or going back to the roots with ubuntu, mainly for learning, dev and ai, maybe gaming as well.

How do you use Ubuntu in these strange times? What makes you stay with it?

Thanks!

In this step-by-step demo, you'll build a fully local AI coding agent on Ubuntu using Pi, Canonical Workshop, and the Qwen3-Coder Inference Snap.

Hope you like it!

I am very new to linux and Ubuntu, Following guides online, I installed Ubuntu Server 24.04.4 and samba-ad-dc I got it working and it has been fine for over 6 months.

I just lost power, rebooted the server and went to login and it flashes the normal screen (I recorded the screen to see what it says) and then kicks me back to login screen.

I tried ctrl-alt-f2 through f6 and logging in again they all do the same thing.

Please help don't know where to go from here.

So i install ubuntu in mi laptop, with 8 ram, for some reason is only showing i have 6 and 1 TB hard drive that i used for games like steam and stuff, but for some reason every time i save it as the default for games it keeps reseting.

the vesion of ubuntu is 24.04.1 x86-64 and my laptop a Lenovo Ideapad Gaming 3, AMD Ryzen 5 4600H

Hey guys, I am using Linux Ubuntu 22.04 as dual booted and I didn’t really find useful or good customisation options or tricks
Would love to see how your desktop or over Ubuntu looks like and if I find it acc to my taste would love a tutorial on how to get it.

Laptop - Lenovo Thinkpad X13 Gen 1

because I see Ubuntu is the best if you exclude snap and Ubuntu pro and telemetry

is there any Ubuntu have uninstalled snap and Ubuntu Pro and telemetry

and I want it perfect UI because mint have bad UI experience for me

i'm currently on 26.04, and up until like a week ago i could draw on csp through bottles. then i upgraded, and now when i open csp my tablet (a very old wacom intuos) moves the cursor but can't interact with anything unless i click with my actual trackpad. the cursor also doubles when i move my pen; one following the pen and another one that stays where i last left the trackpad one. also tried using krita but same problem.

the tablet works fine in every other app and i'm pretty sure this isn't a driver problem because i can draw in photopea just fine.

i've changed settings in csp to "use mouse mode in tablet driver settings" and reinstalled ubuntu but it still doesn't work

should i just dual boot at this point

Ubuntu tends to prioritize conservative power management configurations, often maintaining ASPM and P-State policies that are not geared toward energy savings ostensibly to maximize compatibility and avoid stability issues. However, this strategy can result in inefficient dynamic management: in certain scenarios, the CPU maintains unnecessarily high frequencies and performance levels during light desktop tasks, failing to properly leverage available EPP (Energy Performance Preference) settings. This forces users to manually modify profiles and parameters that should have been reasonably configured from the initial installation. Another weak point is the `s2idle` sleep state, where Ubuntu can exhibit high power consumption even with the laptop lid closed. While firmware and drivers may contribute to this issue, the way the operating system coordinates the freezing of user-space processes, the suspension of devices, and the transition of the platform into low-power states also plays a critical role. In any case, it is fair to question why Ubuntu consistently fails to deliver competitive power management right out of the box especially given the resources and experience at Canonical’s disposal. If other distributions can achieve better battery life using default settings without requiring manual tweaks then Ubuntu should invest more effort into optimizing its power policies, validating `s2idle` behavior, and ensuring that devices reach the appropriate sleep states, rather than shifting the burden of fixing these shortcomings onto the user. And the worst part is that there are already community solutions that should have been included in Ubuntu from the start, since it's a distribution for beginners, the TLP should already be configured. It is clear that, despite using generic profiles, they have failed to follow even the most fundamental principles of power management.

I just downloaded Ubuntu and I am unable to connect to Wi-Fi. It shows that Wifi Adapter is not found. I tried to search for a solution but couldnt find one so I asked Gemini for a sol. Should I try it out? Is it safe?

I have a media tek chip MT7902

There’s no Auth App available to download?
I’m trying to add a plugin for Firefox or Brave, but can’t find one .

Has anyone gotten it to work?

Hi! I’m trying to diagnose a repeatable performance problem on my Acer laptop running Ubuntu. It affects mostly my gaming performance (CPU clocks at 400 MHZ which leads to high CPU usage and low FPS).

Hardware and software details:

• Laptop: Acer Nitro Lite 16, NL16-71G
• CPU: Intel Core i5-13420H - 4 P-cores + 4 E-cores, 12 threads
• GPU: NVIDIA RTX 3050 Laptop GPU, 6 GB, plus Intel integrated graphics
• RAM: 16 GB
• Display: 1920 × 1200, 165 Hz
• BIOS: V1.19
• OS: Ubuntu 26.04.1 LTS
• Kernel: 7.0.0-38-generic
• Desktop: Sway 1.11 / Wayland
• NVIDIA driver: 595.99.02
• Power profile: performance, confirmed with powerprofilesctl get
• Game: Warcraft III: Reforged through Lutris

How to reproduce

1. Reboot with the charger connected.
2. Launch Lutris and Warcraft III: Reforged.
3. The game runs at approximately 160 FPS, and Firefox/the desktop also becomes noticeably sluggish. CPU load is around 60-70% although the game is very lightweight.
4. Unplug the charger briefly while the game is running for about ~5-6 seconds, then reconnect it.
5. FPS jumps to approximately 300–330, and desktop responsiveness improves, also CPU load lowers to 15-20%. The improvement remains after reconnecting AC power.

I can get 300 FPS even with running on battery, before I reconnected the charger again.

Unplugging/replugging on the desktop before launching the game itself did not fix it in one test. Only when game is launched and I'm getting 160 FPS at 400-1000 MHZ - I replug the charger and plug in it again, and CPU MHZ increases to around ~2500-3800 and FPS increases to 300+, also CPU load decreases to only 15-20%.

Measurements:

In the slow state, CPU readings are often around 1.1–2.0 GHz, with roughly 50–60% overall CPU usage. In the responsive state, usage has been around 15–20%.

Earlier checks showed CPU clocks around 3–3.6 GHz after reconnecting power. However, some later /proc/cpuinfo snapshots also showed lower clocks in the fast state, so I haven’t established that CPU frequency alone explains the problem.

One pair of measurements, collected while the game was in the foreground:

scaling_max_freq remained unchanged in both states:

• P-core policies: 4600000 kHz
• E-core policies: 3400000 kHz

What I have checked

• The game appears on the RTX 3050 in nvidia-smi.
• nvidia-powerd is installed and normally running. Temporarily stopping it and starting it again did not improve FPS withouht unplugging the charger.
• The power profile remains performance before and after reconnecting.
• The issue occurs after a reboot without needing a suspend/resume cycle.
• In one test, suspending and resuming after restoring performance did not bring the slowdown back.

Has anyone experienced this on Acer gaming laptops, or on another Intel/NVIDIA laptop under Linux?

What would be the most useful logs or measurements to distinguish a firmware power-limit issue from Linux power management or charger detection? I’d prefer to establish the cause before changing firmware or disabling any protection mechanisms.

P.s. On Windows I don't have a FPS issue, so it's not a mechanical/physical defect of the charger or laptop.

P.s.s. I don't know, if I can fix this issue, but at least I want to understand, why this issue happening at all.

Appreciate any help!

Hey, I need to set up a VM for 24.04 LTS to access my college's Citrix environment.

Citrix currently does not support 26.04 LTS and when I go into overview mode it tricks my Citrix session into thinking my super key is held down, and that will even follow me to other devices if I don't end the session so I need 24.04 but can't find the download. Everything I google looks like a pirate website so idk... If someone can please provide a safe link that would be much appreciated!!

This entire time I thought the screenshot on ubuntu.com was an animated webp. But it's actually html. The time and date also follows your system. Just felt like sharing my discovery
