Random crashes on an NVIDIA RTX 2060 Super in Arch Linux are typically caused by driver instability, PCIe power management conflicts, or insufficient cooling rather than hardware failure. The most reliable fix involves updating to the latest proprietary drivers, disabling aggressive PCIe ASPM states, and ensuring your system provides stable power delivery during high-load scenarios.
Understanding the Crash Symptoms
Before applying fixes, it is crucial to distinguish between a complete kernel panic, a Xorg/Wayland compositor crash, and a hard reset. A blue screen of death (BSOD) is technically a Windows concept; on Linux, you will likely see a black screen, a frozen display server, or a kernel log dump in the virtual console (TTY). If the system reboots instantly without logging errors, the issue may be electrical. If the display freezes but the system remains responsive via SSH, the GPU driver has hung. Common symptoms include artifacts before the crash, fan speed spiking to maximum immediately prior to failure, or random application termination. These signs often point to thermal throttling limits being hit or voltage drops under load. It is important to check if the crashes occur only during specific workloads, such as gaming or rendering, versus idle states. This distinction helps narrow down whether the problem lies with software configuration or physical hardware constraints.

Arch Linux users benefit from rolling releases, but this also means staying current with NVIDIA’s proprietary drivers is essential. The open-source Nouveau driver is generally unstable for modern cards like the RTX 2060 Super during heavy loads. Ensure you have installed thenvidia package along with nvidia-utils and nvidia-settings. Avoid using the nvidia-open-dkms package unless you have specifically tested it for stability, as it can sometimes introduce regressions.
Run a full system update to ensure your Linux kernel matches the requirements of the latest driver version. Newer kernels often include better support for PCIe power management features that prevent sudden drops. You can check your current driver version by running nvidia-smi in the terminal. If the output shows the driver version and no errors, the software layer is likely functioning correctly at a basic level.
If you recently updated the kernel and started experiencing crashes, consider booting into an older kernel from your GRUB menu to test for regression. This step isolates whether the issue is tied to a specific kernel update or the driver itself. Keep in mind that mixing different driver versions or leaving residual configuration files from previous installations can cause conflicts. Clean removal and reinstallation of the NVIDIA packages may be necessary if you suspect corruption.
Disabling Aggressive Power Management
One of the most common causes of random GPU crashes on Linux is the interaction between the operating system’s power management and the PCIe bus. The Advanced Switching Power Management (ASPM) feature allows devices to enter low-power states when idle. However, some NVIDIA GPUs struggle to wake up quickly enough from these states, leading to timeouts and system hangs. To disable ASPM, you need to modify your bootloader parameters. Edit your GRUB configuration file, typically located at/etc/default/grub. Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT and append pcie_aspm=off to the existing string. After saving the file, regenerate your GRUB configuration by running sudo grub-mkconfig -o /boot/grub/grub.cfg on BIOS systems, or update your EFI entries accordingly. Reboot your system to apply the changes.
Another related setting is the NVIDIA-specific power management option. You can create a custom configuration file in /etc/modprobe.d/ named nvidia-pm.conf and add the line options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222". This forces the GPU to stay in its highest performance state, eliminating latency spikes associated with power scaling. While this increases power consumption and heat output, it significantly improves stability for many users experiencing random freezes.

Monitoring Temperatures and Voltages
Even with software fixes, physical limitations play a role in stability. Use tools likenvtop or sensors to monitor your GPU temperature and power draw in real-time. If temperatures consistently exceed 85°C under load, thermal throttling may be triggering protective shutdowns. Inno3D cards, like other manufacturers, rely on adequate case airflow to maintain optimal operating conditions.
Check if your fans are spinning correctly and if the heatsink is free of dust. If the card is old, repasting the thermal compound might be necessary. Additionally, verify that your power supply unit (PSU) is providing stable voltage on the 12V rail. Weak PSUs can cause voltage droops when the GPU demands sudden bursts of power, leading to immediate crashes. Using a multimeter or PSU monitoring software can help identify these electrical issues.
Checking System Logs for Errors
When a crash occurs, the Linux kernel logs valuable information that can pinpoint the root cause. Access the logs usingjournalctl -k to view kernel messages. Look for lines containing "NVRM", "Xid", or "GPU fault". The Xid codes are specific error identifiers used by NVIDIA drivers. For example, Xid 31 indicates a PCIe bus error, while Xid 43 suggests a memory corruption issue.
If you find frequent Xid errors, they provide direct clues about what went wrong. A Xid 31 often correlates with the PCIe ASPM settings mentioned earlier. A Xid 43 might indicate faulty VRAM or driver bugs. Copying these error messages and searching for them online can lead to community solutions or known bugs in specific driver versions.
It is also useful to check the dmesg output immediately after a reboot following a crash. Sometimes the final few lines of the log contain the smoking gun, such as a watchdog timeout or a hardware interrupt storm. Documenting these logs is essential if you need to seek further help from the Arch Linux forums or NVIDIA support.
