Setting up Ubuntu
Various versions of Ubuntu are certified and supported by Canonical on HP computers. Also, you can buy
select HP computers with certified versions of Ubuntu preloaded and ready to use.
For more information, go to the Ubuntu Desktop certified hardware search page at
arch for your computer product. Ubuntu is available at
no cost fr
Open source graphics drivers
Most distributions of the Linux operating system support graphics hardware through combinations of
software technologies built into the kernel and higher-level graphics applications such as display servers
(Xorg, Wayland) and display managers (Gnome, KDE).
Graphics hardware performance depends upon setup by the running kernel and timing information obtained
by attached display hardware. When the kernel cannot correctly calibrate its initialization of graphics
hardware to available display hardware, the results can yield distorted or blank display screens.
Interaction with open source graphics drivers can occur during:
●
Graphical interactive installation sessions from downloaded Linux distribution media
●
Use of Linux installations not supplemented with vendor-proprietary graphics drivers
In cases of unusable display screens, HP recommends adding the nomodeset option to the kernel boot
parameters to suppress mode-setting driver behavior and prioritize the use of alternate compatible display
drivers. You can usually edit the persistent inclusion of this parameter (in cases of the grub family of boot
loaders) into kernel boot parameters in configuration files usually found in: /etc/default/grub. See your
distribution's documentation for boot loader settings parameters.
NOTE:
Some computer configurations might have graphics cards and CPUs with native integrated graphics
support. Some recent systems might enable integrated graphics simultaneously with discrete graphics cards
instead of hiding the integrated options (a previously common operational mode). In this case, some Linux
installations might select the integrated graphics ports as the default while consoles and displays that are
connected to graphics cards might look blank when started. To disable use of integrated graphics when
additional graphics cards are present, clear the Integrated Video option in the Advanced / Built-In Device
Options menu for the F10 Setup Menu of system BIOS options.
Proprietary graphics drivers
Read this section to learn about proprietary graphics drivers.
Most HP computers can be ordered with graphics cards that have been through extensive
verification by HP. For a list of supported cards, see Linux Hardware Matrix for HP Workstations at
NOTE:
Not all graphics cards are supported on every computer. Limitations generally occur for cards that
consume large amounts of power in lower-power computers.
HP supports third-party proprietary graphics drivers. For drivers that have been tested, go to
ollow the on-screen instructions to find your product and locate the
documentation.
