What we need to do is instruct the touchscreen to rotate its matrix when the display does, which means it'll work in both portrait and landscape modes. In the case of the Linx 1010, this reveals it has a Goodix Capacitive TouchScreen. Moving on, let's get the touchscreen working properly.
Reboot, and you'll reduce the potential for system lockups, but note the kernel parameter increases power consumption and impact on battery life, which is a shame because the ACPI features still don't work, meaning that the power settings remain inaccurate: battery life is always rated at 100%, even when it's clearly not. GRUB_CMDLINE_LINUX_DEFAULT="intel_idle.max_cstate=0 quiet"
Look for the line marked GRUB_CMDLINE_LINUX_DEFAULT and change it to this: There may also be issues with stability that you can fix with a rough and ready workaround by configuring Grub: You'll lose support for the internal SDIO wireless card (we had to plug in a spare USB Wi-Fi adaptor to get internet connectivity back) and the sound is no longer recognised. We'll fix that shortly.įirst, you need to be aware of the drawbacks. You'll discover you now have touch support at the login screen (this is single touch, not multi-touch), but once you log in and the display rotates you'll find it no longer works correctly. $ sudo dpkg -i linux-headers-4.3*.deb linux-image-4.3*.deb We picked kernel 4.3.3 – to install this, type the following into a Terminal: If you're desperate to get touchscreen support for your tablet, and you've got a spare USB Wi-Fi adaptor handy (because updating the kernel breaks the internal Wi-Fi adaptor), then upgrade your kernel to 4.1 or later.
We're hoping the final release of 16.04 may yield more possibilities, but if you can't wait for that and are willing to run the risk of reduced stability read on. We were thwarted in this respect – touch support is present, but we had to manually add the bootia32.efi file to the EFI\Boot folder to get the live environment to boot, and installation failed at varying points, probably due to the spotty internal flash drive support.
