Pens and graphics tablets on Linux

Summary

Wacom describes its long-standing collaboration with the Linux community on free pen and tablet support. Linux Wacom drivers have been developed as free software for many years. The kernel supports numerous USB and Bluetooth tablets directly.

Ideas

  • Kernel drivers pass raw data from pen and tablet to the input stack.
  • libwacom provides device descriptions to desktop and configuration tools.
  • Wayland compositors must correctly pass on pressure, tilt, buttons and mapping.
  • Upstream contributions reach many distributions without separate vendor drivers.
  • Open tests link hardware generations with different desktop environments.

Insights

  • Good device support arises across several projects rather than through a single driver.
  • Upstream work extends the life of hardware beyond the vendor's product cycles.
  • Professional input requires consistent calibration from the kernel to the application.

Facts

  • libwacom contains metadata and layout information about supported devices.

Recommendations

  • Check the tablet model, kernel, libwacom and desktop protocol together.
  • Report bugs with the device ID, connection type and input events.

Main development phase of Linux kernel 2.6.36 completed

With Linux 2.6.36-rc1, the merge window, in which most new features enter the main branch, ended in August 2010. Among other things, the AppArmor security framework was accepted after years of attempts, as were fanotify for virus scanners and a driver for Intel’s Intelligent Power Sharing. As with 2.6.35, Torvalds wanted to accept strictly only bug fixes in the following stabilisation phase.

Linux kernel 2.6.35 released

In August 2010, Linus Torvalds released Linux kernel 2.6.35, just under eleven weeks after 2.6.34. New features included power saving for Radeon graphics and H.264 decoding on Intel’s Ironlake processors. Changes to the network stack and to the use of CPU power-saving states were expected to speed up some systems considerably.
