# Fix common Ubuntu performance issues on Lenovo Legion laptop with NVIDIA GPU
|
||||
#
|
||||
# System: Ubuntu 24.04, AMD Ryzen 7 4800H, RTX 2060 Mobile, 32GB RAM, NVMe SSD
|
||||
#
|
||||
# Issues addressed:
|
||||
# 1. NetworkManager-wait-online.service → adds ~6.7s to every boot for no benefit
|
||||
# 2. vm.swappiness=60 → too aggressive for 32GB RAM + NVMe, wastes I/O on swap
|
||||
# 3. NVIDIA persistence mode off → GPU re-initializes on every nvidia operation
|
||||
# 4. No earlyoom → system can hard-freeze under memory pressure (OOM killer too slow)
|
||||
# 5. Failed SSSD systemd units → retry loops waste CPU, journal space
|
||||
# 6. Journal potentially bloated → wastes disk I/O
|
||||
# 7. No VFS/dirty page tuning → suboptimal for dev workloads on NVMe
|
||||
#
|
||||
# Every change creates an entry in the undo script for easy reversal.
|
||||
#
|
||||
# Usage:
|
||||
# sudo ./fix_ubuntu_performance.sh # Apply all fixes
|
||||
# sudo ./fix_ubuntu_performance.sh --dry-run # Show what would be done
|
||||
# sudo ./fix_ubuntu_performance.sh --undo # Reverse all changes
|
||||
# sudo ./fix_ubuntu_performance.sh -h # Show help
|
||||
#
|
||||
# Safe to re-run: all fixes are idempotent.

Usage: fix_ubuntu_performance.sh [OPTIONS]
|

Options:

--dry-run Show what would be done without making changes

--undo Reverse all changes (uses generated undo script)

-i, --interactive Prompt before each fix
|
||||
-h, --help Show this help message
|
||||
|
||||
Fixes applied:
|
||||
1. Disable NetworkManager-wait-online.service (saves ~6.7s boot)
|
||||
2. Tune vm.swappiness to 10 + vm.vfs_cache_pressure to 50 + dirty page tuning
|
||||
3. Enable NVIDIA persistence mode via systemd
|
||||
4. Install earlyoom (prevents OOM hard-freezes)
|
||||
5. Mask failed SSSD socket/service units (stop retry waste)
|
||||
6. Vacuum systemd journal + set 300M cap
|
||||
7. Set NVMe I/O scheduler to kyber (if available, else none)
|
||||
|
||||
All fixes are idempotent and safe to re-run.
|
||||
Run with --undo to reverse all changes.
