| Additional notes that may help set up a graphic system: | Additional notes that may help set up a graphic system. Setting up graphics in dCore is similar to getting graphics running from most any other minimal Linux installation. As such a large variety of hardware is available and packages vary between dCore flavours (ie. older/newer Debian vs Ubuntu packages), internet searching for missing packages or configuration may sometimes be required. Post on the forum if unable to get dCore graphics running properly. |
| *The extension being installed may contain video drivers plus additional data. For example, //xserver-xorg-video-intel// also contains the packages //xserver-xorg-video-////vesa// and //xserver-xorg-////input-{////all,////wacom,mouse,vmmouse,synaptics}//. | *The extension being installed may contain video drivers plus additional data.

| *Extensions to identify hardware, such as //pciutils//, can be removed when no longer required. | |

| *Although not typically required an xorg.conf file may be needed to get graphics, achieve desired resolution and colour depth or enable graphic driver options. See the [[http://wiki.tinycorelinux.net/dcore:xorg-video_driver_packages?&#dcore_xorgconf_example|dCore xorg.conf example]] below. | *Extensions to identify hardware, such as //pciutils//, can be removed when no longer required. |
| *Review this [[http://wiki.tinycorelinux.net/dcore:faq#help_i_followed_the_documentation_but_can_t_boot_into_graphics|dCore graphics FAQ]] entry for more information. | *Review this [[http://wiki.tinycorelinux.net/dcore:faq#help_i_followed_the_documentation_but_can_t_boot_into_graphics|dCore graphics FAQ]] entry if unable to get graphics running. |
| | *Review /var/log/Xorg.0.log for hints after a failed ''startx'' attempt. |
| | *If system boots into graphics but not desired resolution, run ''xrandr'' to determine available default resolutions. If the desired resolution is available, test enter the appropriate resolution (eg. ''xrandr -s 1280x800''). If adequate then add this is an ~/.X.d/ entry. If a monitor resolution other than an available default ''xrandr'' output is desired, additional xrandr commands will be required or consider using an xorg.conf file (see below). Helpful ''xrandr'' links: [[ftp://www.x.org/pub/X11R7.5/doc/man/man1/xrandr.1.html|xrandr man page]], [[https://pkg-xorg.alioth.debian.org/howto/use-xrandr.html|xrandr guide]]. |
| | *Although not typically required an xorg.conf file may be needed to get graphics, achieve desired resolution and colour depth or enable graphic driver options. For example, an old Intel i810 graphic system required the [[http://wiki.tinycorelinux.net/dcore:xorg-video_driver_packages?&#dcore_xorgconf_example|dCore xorg.conf example]] file below, including the "DRI" "FALSE" entry, to obtain any graphics in dCore-xenial. |
| | *To exit graphics when tweaking monitor resolution or xorg.conf configuration, run ''exittc'' or select //Exit// from a supported Window Manager, then select //Exit to Prompt//. This will exit Xorg and the Window Manager and return to a TTY. Enter ''startx'' to restart graphics and Window Manager. |
| | *Various software to test and benchmark graphic performance can be imported from the respective Debian/Ubuntu repository, such as GtkPerf, mesa-utils (provides glxgears) and nvidia-detect (requires loading Bash). This may help to identify problems and deficiencies. For example, a failed attempt to run ''glxgears'' on the Intel i810 system mentioned above required loading //libgl1-mesa-swx11// in addition to //xorg-intel// and //graphics-3.16.6-tinycore//. |
