xorg-x11-drv-i810 is an Intel integrated graphics video driver for the X.Org implementation of the X Window System.
When switching from the X server to a virtual terminal (VT) on a Lenovo ThinkPad T510 laptop, the screen can remain blank. Switching back to the X server will restore the screen.
Running a screensaver or resuming a suspended laptop with an external monitor attached may result in a blank screen or a brief flash followed by a blank screen. If this occurs with the screensaver, the prompt for your password is being obscured, the password can still be entered blindly to get back to the desktop. To work around this issue, physically disconnect the external monitor and then press the video hotkey (usually Fn-F7) to rescan the available outputs, before suspending the laptop.
The following known issues apply to the Intel 64 and AMD64 architectures:
If your system uses an Intel 945GM
graphics card, do not use the
driver. You should use the default
driver instead. (BZ#468218
On dual-GPU laptops, if one of the graphics chips is Intel-based, the Intel graphics mode cannot drive any external digital connections (including HDMI, DVI, and DisplayPort). This is a hardware limitation of the Intel GPU. If you require external digital connections, configure the system to use the discrete graphics chip (in the BIOS). (BZ#468259
