These tools were created during extensive testing of OTD integration. - -## Why This Folder Exists - -We attempted to make OpenTabletDriver work with Paintstorm in the distrobox container. After extensive testing and debugging, we discovered **multiple unfixable issues**: - -### Issue 1: Mouse Freezing -**Symptom**: Mouse freezes while drawing with pen, unfreezes on Alt+Tab -**Cause**: X11 pointer grabbing conflict between OTD virtual device and mouse -**Scripts**: `diagnose-pointer-freeze.sh`, `fix-pointer-freeze.sh` - -### Issue 2: Second Launch Failure -**Symptom**: Pressure works on first launch, fails on second launch -**Cause**: Native devices get re-enabled between launches -**Scripts**: `test-paintstorm-relaunch-issue.sh`, `track-device-state-changes.sh` - -### Issue 3: Device Recognition -**Symptom**: Paintstorm doesn't recognize OTD virtual device for pressure -**Cause**: Paintstorm expects specific device names/types -**Scripts**: `check-which-device-used.sh`, `test-which-device-active.sh`, `test-pressure-data.sh` - -## Recommendation - -**Use native HID instead of OpenTabletDriver.** - -See `../native-hid-tablet-mapping/` for the working solution. - -Native HID provides: -- ✅ Full pressure sensitivity (0-8191 levels) -- ✅ Tilt support -- ✅ Button mapping with xbindkeys -- ✅ No mouse freezing -- ✅ No second-launch issues -- ✅ Reliable, stable operation - -## When to Use These Tools - -Only use these diagnostic tools if you: -1. Want to understand why OTD doesn't work -2. Are debugging OTD for other applications (not Paintstorm) -3. Need to document OTD issues for bug reports - -**For Paintstorm use, go to `../native-hid-tablet-mapping/` instead.** - -## Diagnostic Tools - -### Device Detection & Testing -- **`check-which-device-used.sh`** - Shows which device is active (native vs OTD virtual) -- **`test-which-device-active.sh`** - Alternative device activity test -- **`test-pressure-data.sh`** - Verify if OTD virtual device sends pressure data - -### Mouse/Pointer Issues -- **`diagnose-pointer-freeze.sh`** - Diagnose mouse freezing issues -- **`fix-pointer-freeze.sh`** - Interactive menu to fix pointer conflicts - -### Launch Issues -- **`test-paintstorm-relaunch-issue.sh`** - Test for second-launch failures -- **`track-device-state-changes.sh`** - Track xinput device state changes - -### Compatibility Testing -- **`test-xsetwacom-compatibility.sh`** - Test if xsetwacom works with Huion - -### Wrappers & Guides -- **`paintstorm-with-otd-wrapper.sh`** - Wrapper that ensures OTD config (doesn't fully fix issues) -- **`TABLET-INPUT-GUIDE.md`** - Complete technical guide to OTD vs native HID - -## The Bottom Line - -After creating all these diagnostic tools and testing extensively: - -**OpenTabletDriver is NOT recommended for Paintstorm in distrobox.** - -The issues are fundamental to how X11, distrobox, and Paintstorm interact with input devices. No amount of configuration or scripting fully resolves them. - -**Use native HID** for a superior, hassle-free experience. - -## Technical Summary - -### Why OTD Fails - -1. **Device Grabbing**: OTD takes exclusive hidraw access, making native devices appear active but with no data -2. **Application Recognition**: Paintstorm doesn't recognize OTD virtual devices as pressure-capable -3. **State Persistence**: Device enable/disable states don't persist correctly across application launches -4. **Pointer Conflicts**: X11 master pointer can't properly handle both mouse and OTD virtual device - -### Why Native HID Works - -1. **Direct HID Support**: Generic Linux HID driver provides full pressure and tilt -2. **No Virtualization**: Applications see real hardware devices -3. **Stable State**: No device swapping or enable/disable needed -4. **Standard Protocol**: Uses standard X11 XInput2 protocol - -## Credits - -These diagnostics were created during an extensive effort to make OTD work with Paintstorm. While the effort was ultimately unsuccessful for this use case, the tools may be useful for understanding OTD behavior in other contexts. - -**For actual tablet usage with Paintstorm: Use native HID.** - -See: `../native-hid-tablet-mapping/` @@ -1,411 +0,0 @@ -# Tablet Input Device Guide - OTD vs Native HID - -## Understanding Your Tablet Setup - -Your diagnostic shows a **device conflict** between two input systems.

The one showing events is the active device. - -## Recommendation - -Based on your situation: - -### If you DON'T need OTD features: -**Just use native HID support** (no otd-daemon): -```bash -pkill otd-daemon -~/paintstorm # Pressure works perfectly -``` - -This is simpler and already works. - -### If you DO need OTD features: -**Disable native devices** when OTD is running: -```bash -otd-daemon & -sleep 2 -xinput disable 11 # Native stylus -xinput disable 24 # Native eraser -~/paintstorm # Now uses OTD virtual devices -``` - -## Technical Details - -### Why Both Devices Appear in xinput - -When you see both sets of devices in `xinput list` (with OTD running), it's misleading: - -- **Native devices (id=11, 24)**: Visible in xinput but **INACTIVE** (no data flow) -- **Virtual devices (id=25, 27)**: Visible and **ACTIVE** (receiving OTD processed data) - -The native devices appear because: -1. The kernel still detects the USB tablet -2. The HID subsystem still creates input devices -3. But OTD has grabbed `/dev/hidraw*` with exclusive access -4. So the native devices get no data - -It's like having two phone lines but only one is connected. - -### Why wacom/hid_uclogic are Blacklisted - -Your `/etc/modprobe.d/99-opentabletdriver.conf` blacklists: -- `wacom` - Wacom-specific kernel driver -- `hid_uclogic` - Generic Chinese tablet driver (for Huion/XP-Pen/etc) - -This is correct for OTD because: -1. Those drivers would conflict with OTD -2. Generic HID support (not blacklisted) still works -3. Generic HID provides basic pressure/tilt -4. OTD provides advanced features - -You're using the **generic Linux HID driver** (not hid_uclogic), which is why pressure works without OTD. - -## Summary - -``` -┌─────────────────────────────────────────────────┐ -│ Without OTD (Current working state) │ -├─────────────────────────────────────────────────┤ -│ Tablet → hidraw → Generic HID → id=11 → │ -│ Paintstorm ✓ WORKS │ -└─────────────────────────────────────────────────┘ - -┌─────────────────────────────────────────────────┐ -│ With OTD (Current broken state) │ -├─────────────────────────────────────────────────┤ -│ Tablet → hidraw → OTD → id=25 │ -│ ↘ │ -│ id=11 (dead) │ -│ ↓ │ -│ Paintstorm ✗ BROKEN │ -└─────────────────────────────────────────────────┘ - -┌─────────────────────────────────────────────────┐ -│ With OTD + disabled native (FIX) │ -├─────────────────────────────────────────────────┤ -│ Tablet → hidraw → OTD → id=25 → Paintstorm │ -│ (id=11 disabled via xinput) ✓ WORKS │ -└─────────────────────────────────────────────────┘ -``` - -**Your choice:** -- **Simple**: Don't use OTD, just use native HID (already works) -- **Advanced**: Use OTD + disable native devices via xinput - -Choose based on whether you need OTD's features (custom curves, remapping, area config). - -## Known Issue: Mouse Freezing with OTD - -### Symptoms -- Pen/tablet works correctly -- Mouse freezes when you draw with the pen -- Mouse unfreezes when you Alt+Tab or change window focus -- This repeats every time you use the pen - -### Cause -This is an X11 **pointer grabbing conflict**. When you use the pen: -1. The tablet device grabs pointer focus -2. X11 suppresses mouse events (thinking pen = exclusive input) -3. Window focus change releases the grab -4. This happens because X11 doesn't expect both devices active simultaneously - -### Quick Fixes - -#### Fix 1: Use the automated fix script -```bash -./fix-pointer-freeze.sh -# Choose option 1: Disable all native Huion devices -``` - -#### Fix 2: Manual disable -```bash -# Disable native devices -xinput disable 11 # Native stylus -xinput disable 24 # Native eraser - -# Verify they're floating (disabled) -xinput list | grep floating -``` - -#### Fix 3: Restart OTD daemon -```bash -pkill otd-daemon -otd-daemon & -sleep 2 -xinput disable 11 -xinput disable 24 -``` - -#### Fix 4: Switch back to native HID -If the freeze persists, just use native HID (it works perfectly): -```bash -pkill otd-daemon -xinput enable 11 -xinput enable 24 -~/paintstorm # Pressure works! -``` - -### Diagnostic Tool - -To diagnose the pointer freeze issue: -```bash -./diagnose-pointer-freeze.sh -``` - -This will show you: -- Which devices are attached to the master pointer -- Whether there are device conflicts -- Current pointer grab status -- Recommended fixes - -### Why This Happens - -X11 has a single "master pointer" that controls the cursor. When multiple pointer devices (mouse + tablet) are active: -- Some applications grab the pointer exclusively when the pen is in use -- This prevents the mouse from generating events -- Releasing focus (Alt+Tab) releases the grab -- This is a limitation of X11's input architecture - -### Permanent Solution - -If you need OTD and want to avoid this issue permanently: - -**Option A: Create a wrapper that ensures native devices stay disabled** -```bash -cat > ~/paintstorm-otd-fixed << 'EOF' -#!/bin/bash -# Ensure OTD is running -if ! pgrep -f otd-daemon > /dev/null; then - otd-daemon & - sleep 2 -fi - -# Always disable native devices before launching -xinput disable 11 2>/dev/null || true -xinput disable 24 2>/dev/null || true - -# Launch Paintstorm -~/paintstorm -EOF - -chmod +x ~/paintstorm-otd-fixed -``` - -**Option B: Use native HID (recommended if you don't need OTD features)** -```bash -# Stop OTD permanently -pkill otd-daemon - -# Don't start it on boot -# Remove from startup applications if configured - -# Use Paintstorm with native HID -~/paintstorm # Works perfectly -``` - -### Technical Details - -The freeze happens because: -1. X11 uses a "core pointer protocol" where one device controls the cursor -2. When you have multiple pointer devices (mouse + tablet), X11 must decide which is active -3. Applications can request "pointer grabs" for exclusive input -4. Paintstorm (or X11) is grabbing the pointer when the pen is active -5. This suppresses mouse events until the grab is released -6. Alt+Tab changes window focus, which releases pointer grabs - -Modern Wayland compositors handle this better, but Paintstorm requires X11. - -## Choosing Your Configuration - -### Use Native HID If: -- ✅ Pressure and tilt already work -- ✅ You don't need custom pressure curves -- ✅ You don't need pen button remapping -- ✅ You want simple, trouble-free setup -- ✅ You experience mouse freezing with OTD - -### Use OTD If: -- ✅ You need custom pressure curves -- ✅ You need pen button remapping -- ✅ You need precise tablet area configuration -- ✅ You're willing to disable native devices and troubleshoot pointer issues -- ✅ You need features not available in native HID - -**Most users should use native HID** - it works out of the box with full pressure and tilt support. @@ -1,223 +0,0 @@ -#!/bin/bash -# Check which input device is actually receiving events -# Usage: ./check-which-device-used.sh [--verbose] - -RED='\033[0;31m' -GREEN='\033[0;32m' -YELLOW='\033[1;33m' -BLUE='\033[0;34m' -BOLD='\033[1m' -NC='\033[0m' - -VERBOSE=false -if [[ "$1" == "--verbose" || "$1" == "-v" ]]; then - VERBOSE=true -fi - -echo "==========================================" -echo "Tablet Device Activity Test" -echo "==========================================" -echo "" - -# Get device information -NATIVE_STYLUS=$(xinput list | grep -i "HUION.*Pen stylus" | grep -v "Virtual" | head -1) -NATIVE_STYLUS_ID=$(echo "$NATIVE_STYLUS" | grep -o 'id=[0-9]*' | cut -d= -f2) -NATIVE_STYLUS_NAME=$(echo "$NATIVE_STYLUS" | sed 's/.*↳ //' | sed 's/id=.*//' | xargs) - -VIRTUAL_STYLUS=$(xinput list | grep -i "OpenTabletDriver.*stylus" | head -1) -VIRTUAL_STYLUS_ID=$(echo "$VIRTUAL_STYLUS" | grep -o 'id=[0-9]*' | cut -d= -f2) -VIRTUAL_STYLUS_NAME=$(echo "$VIRTUAL_STYLUS" | sed 's/.*↳ //' | sed 's/id=.*//' | xargs) - -OTD_RUNNING=$(pgrep -f otd-daemon > /dev/null && echo "YES" || echo "NO") - -# Test devices -echo "Testing devices (move your pen for 5 seconds)..." -echo "" - -NATIVE_ACTIVE="N/A" -NATIVE_EVENTS=0 -VIRTUAL_ACTIVE="N/A" -VIRTUAL_EVENTS=0 - -if [ -n "$NATIVE_STYLUS_ID" ]; then - echo -n "Testing native device...
