Xubuntu(XFCE)搭配Intel Graphics启动异常求助

Hey there, let's work through this frustrating display issue together—it sounds like a recent update threw a wrench into your Intel graphics setup. Here's a step-by-step breakdown to diagnose and fix it:

1. Dig into critical Xorg error logs #

Your login loop when using the second monitor is almost certainly tied to a fatal Xorg error. First, run the command you mentioned and share the full output—this will tell us exactly what's breaking the display server:

cat /home/dominik/.local/share/xorg/Xorg.2.log | grep EE

Keep an eye out for errors related to i915 (Intel's kernel driver) or EDID (display identification) issues—those are common culprits for monitor-related login loops.

2. Verify Intel driver and kernel compatibility #

Even though lshw -C video detects your GPU, the driver might be misaligned with your kernel (especially if you updated recently):

• Check if the Intel kernel module is loaded:

  lsmod | grep i915
  

  If it's missing, try loading it manually and note any errors:

  sudo modprobe i915
  

• Compare your kernel version with the driver module version to spot mismatches:

  modinfo i915 | grep -E 'version|vermagic'
  uname -r
  

  If they don't match, try rebooting into an older kernel (from your GRUB menu)—this would confirm a bad kernel update is the root cause.

3. Fix the login loop and second monitor issue #

Option A: Reset display configuration

Corrupted monitor settings often trigger login loops. Delete the saved config and let the system re-detect your displays:

rm ~/.config/monitors.xml

Reboot, then reconnect your second monitor and let the system set it up fresh.

Option B: Switch to a more stable open-source driver

The proprietary Intel driver can sometimes conflict with newer kernels. Try switching to the modesetting driver, which has better compatibility for most Intel GPUs:

sudo apt remove xserver-xorg-video-intel

Your system will automatically fall back to modesetting—reboot and test both single and dual monitor setups.

Option C: Reinstall the Intel driver

If you want to stick with the Intel driver, reinstall it to fix any corrupted files from the update:

sudo apt reinstall xserver-xorg-video-intel

4. Resolve the "system application issues" alerts #

Once you fix the display problem, these alerts might disappear on their own. If not, pull the system error logs to identify the faulty apps:

journalctl -p 3 -xb

This shows critical system errors. Look for the apps mentioned in the alerts, then reinstall them—for example, if it's a GNOME component:

sudo apt reinstall gnome-shell
