Solving Ubuntu 18.04 Freezing Issues on Dell XPS 9360

When working with Ubuntu 18.04 on the Dell XPS 9360, it's common to experience freezing issues. This can be frustrating and disruptive. However, by identifying and addressing the underlying causes, you can resolve these problems and enhance your experience. Below, we explore the most common reasons for freezing and provide actionable solutions.

Common Causes

Graphics Driver Issues

The integrated Intel graphics or NVIDIA drivers can sometimes cause freezing due to incorrect functionality. The latest drivers are always recommended to ensure optimal performance and fix any known bugs.

Solution: Ensure you have the latest drivers installed. To check for updates:

sudo apt updatesudo apt upgrade

NVIDIA users should consider installing the proprietary drivers:

sudo ubuntu-drivers autoinstall

Kernel Version

Older kernel versions might not be compatible with newer hardware, leading to freezing. Therefore, upgrading to a more recent kernel can resolve the issue.

Solution: Install a newer kernel version:

sudo apt install linux-generic-hwe-18.04

Power Management Settings

Some power management features can cause instability, leading to freezing. Disabling these features can help stabilize the system.

Solution: In the BIOS settings, disable features like Intel Speed Step or hybrid graphics if applicable.

Hardware Compatibility

Specific hardware components, such as Wi-Fi or Bluetooth adapters, might not be fully compatible with Ubuntu. Checking the Ubuntu forums for known issues and using alternative drivers can resolve these problems.

Solution: Research and install appropriate drivers for any problematic hardware components.

File System Issues

File system corruption can cause system freezing. Regularly checking the file system can prevent these issues from arising.

Solution: Run a file system check:

sudo fsck -f /dev/sdX

Replace /dev/sdX with your actual partition.

Memory Issues

Faulty RAM can lead to system freezes. Running a memory test using Memtest86, available in the GRUB menu, can help identify and fix this problem.

Solution: Use Memtest86 to run a memory test.

Swap Space

Insufficient swap space can cause freezing under heavy load. Ensuring you have enough swap space configured can prevent this.

Solution: Create a swap file if necessary:

sudo fallocate -l 4G /swapfilesudo chmod 600 /swapfilesudo mkswap /swapfilesudo swapon /swapfile

System Logs

Checking system logs can help identify errors that occur before the freeze. This can provide clues on what is causing the issue.

Solution: Use the following command to view logs from the previous boot:

journalctl -b -1

Conclusion

If the above solutions do not resolve the issue, consider upgrading to a newer version of Ubuntu. Newer releases often provide better support and performance for the XPS 9360 hardware.
