Some laptops have a touch pad controller and sometimes the files that control the touch pad are corrupted or removed. If your touch pad has stopped working it may be that they need a new driver which is what you get if you download this file.
A great many laptops use the same software to transmit and interpret signals from the touch pad to the processor. The Synaptics Touchpad Driver is used in many of those laptops even though the laptops are manufactured by different companies. Installing this piece of software may make your touch pad work again and the step-by-step installation instructions make installing the drivers very straightforward. The drivers will also give you the option of activating or deactivating your touchpad which is not usually a function that manufacturers leave open for toggling.
The Synaptics Touchpad Driver is perfect for people who have corrupted or removed their current drivers. It is also ideal for people who are updating their laptop who are building a new laptop or who are changing out their old touch pad for a new one. Installing the driver is not difficult thanks to the step-by-step installation instructions that appear on the screen as you run through the installation process.

To fix this, enable the TearFree option in the driver by adding the following line to your configuration file :. See the original bug report for more info. The intel-driver uses Triple Buffering for vertical synchronization; this allows for full performance and avoids tearing. To turn vertical synchronization off e. On some systems this can cause issues such as this.
To switch back to DRI2 add the following line to your configuration file :. For the modesetting driver, this method of disabling DRI3 does not work. Should you experience missing font glyphs in GTK applications, the following workaround might help. See also FreeDesktop bug Alternatively, appending the following kernel parameter seems to work as well:. Some issues with X crashing, GPU hanging, or problems with X freezing, can be fixed by disabling the GPU usage with the NoAccel option - add the following lines to your configuration file :.
This is originally an Intel CPU bug that can be triggered by certain c-state transitions. It can also happen with Linux kernel 3. The kernel option will prevent the freeze by avoiding c-state transitions but will also increase power consumption.
This issue is covered on the Xrandr page. If after resuming from suspend, the hotkeys for changing the screen brightness do not take effect, check your configuration against the Backlight article. If the problem persists, try one of the following kernel parameters :. Also make sure you are not using fastboot mode i This can be fixed by disabling execlist support which was changed to default on with kernel 4. Add the following kernel parameter :. The video output of a Windows guest in VirtualBox sometimes hangs until the host forces a screen update e.
A temporary solution is to disable this feature using the kernel parameter i The update of mesa from version One of the low-resolution video ports may be enabled on boot which is causing the terminal to utilize a small area of the screen. See Kernel parameters for more info. Video port names can be listed with xrandr.
The "Broadcast RGB" property in the Intel driver defines the color range which can be used by the display - either "Limited " which limits the color range for some displays that cannot properly process full range color signals and "Full".
Since kernel 3. If detections faulty falls back to limited color range, it results in weathered colors and grey blacks. There is no way to persist this setting in xorg.
To fix this problem, use the following kernel parameter :. See [1] , [2] , Xorg Installation , and modesetting 4. Note: GuC submission has been completely disabled for the kernel 5. The i module would fail to initialize as shown in system journal. Note: The following requires xfvideo-intel. Note: You might need to add more device sections than the one listed above. This will be indicated where necessary. Warning: Diverting from the defaults will mark the kernel as tainted from Linux 3.
This basically implies using other options than the per-chip defaults is considered experimental and not supported by the developers. This results in messages logged to the system journal similar to this one: kernel: drm: not enough stolen space for compressed buffer, disabling. Enabling frame buffer compression on pre-Sandy Bridge CPUs results in endless error messages: dmesg [ In order to disable it add i Note: This option currently does not work for external displays e.
Warning: Report bugs and regressions regarding the Iris driver here. Some applications might no longer crash, some may start crashing - you probably do not want to set this variable globally.
