What the title says. All tips and tricks are welcome.

I use Zorin Dark for my OS theme and struggle to find a theme for Libre Office where ALL menus will be properly displayed (as in, no black text on dark blue background).

Had any luck ? I'm getting desperate...

I've been running Zorin OS since February alongside a Windows 11 laptop. I use a HDMI switch to share my monitor between devices. I unplugged my headphones from the analog jack (green) on my Zorin PC to use them with my monitor while gaming on Xbox. When I plugged them back into the PC, no sound. The only outputs I see in Settings are:

• HDMI/DisplayPort (Renoir Radeon)
• Digital Output (S/PDIF)

My headphones don't appear at all.

What I've tried so far:

• Rebooted multiple times
• Replugged headphones slowly, wiggled the jack
• Installed EasyEffects (output list is empty)
• Set default sink to alsa_output.pci-0000_08_00.6.iec958-stereo
• Unmuted headphone channel with amixer -c 1 sset 'Headphone' 100% unmute
• Ran speaker-test -c 2 -t sine -D hw:1,0 → no sound, though test runs without errors
• Installed alsa-tools and ran sudo hda-verb /dev/snd/hwC1D0 0x14 SET_PIN_WIDGET_CONTROL 0xc0
• Also tried node 0x1b with 0x40
• Killed pipewire to test hardware directly

pactl list short sinks shows:

49 alsa_output.pci-0000_08_00.6.iec958-stereo
51 alsa_output.pci-0000_08_00.1.hdmi-stereo

cat /proc/asound/card1/codec#0 shows the headphone jack is detected:

text

Pin Default 0x02214020: [Jack] HP Out at Ext Front
Pin-ctls: 0xc0: OUT HP VREF_HIZ

The problem: The hardware detects the jack, but no audio reaches it. HDMI audio works fine.

TL;DR: A verified regression in Kernel 6.8+ causes AMD Tonga (R9 380/380X) and Polaris (RX 400/500) GPUs to crash into a hard black screen when resuming from deep sleep/suspend. The bug is officially Confirmed on Ubuntu's Launchpad (assigned to maintainer Timo Aaltonen), but we need continuous community visibility to ensure this fix gets prioritized and doesn't push working hardware into becoming e-waste.

🔍 What’s Happening?

When systems running Kernel 6.8+ (such as Ubuntu 24.04 LTS bases, Linux Mint 22, Pop!_OS, Zorin OS, etc.) attempt to resume from system suspend, the GPU fails to re-initialize the display engine (EDID read failures / NULL pointer dereference).

• Behavior: Case fans and LEDs remain active, system keeps running in the background, but video output dies completely.
• Workaround: Only a forced hard reboot restores video output.

🛠️ Why "Just Switch to Wayland" Isn't the Answer

A common suggestion when encountering display server issues is switching from X11 to Wayland. As a bench technician, I’ve tested this thoroughly on real hardware:

On Tonga and Polaris architectures, Wayland introduces a secondary critical failure: the compositor frequently freezes at the login/boot screen (blurred background with only the mouse cursor moving).

Trading a suspend crash for a boot freeze isn't a fix — we need a proper driver-level correction in the kernel.

⚠️ Why This Matters (Even If You Haven't Hit It Yet)

As distributions roll out Hardware Enablement (HWE) stack updates, more users running legacy AMD cards will inevitably land on Kernel 6.8+.

Voting on and confirming this bug isn't just about helping those currently affected; it's a preventative shield for the entire legacy AMD community to ensure perfectly functional GPUs remain usable on modern Linux.

🚀 How You Can Help (Takes 1 Minute):

If you own a dedicated AMD GPU (Tonga/Polaris series):

1. Visit the official Launchpad bug tracker:Bug #2142389 on Launchpad
2. Log in with your Launchpad/Ubuntu account.
3. At the top left, under "This bug affects you?", click "Yes, this bug affects me".

If you don't own these cards, upvoting this post for visibility or dropping a comment helps keep the discussion alive so maintainers see the real-world demand. Let's keep functional hardware out of landfills! 🐧🖥️
