Appendix D. Random Bits Certain kernel modules must be loaded in order for your mouse to work. In most cases the correct modules are autodetected, but not always for old-style serial and bus mice$^{1}$, which are quite rare except on very old computers. Summary of Linux kernel modules needed for different mouse types: To load a mouse driver module, you can use the modconf command (from the package with the same name) and look in the category kernel/drivers/input/mouse . A standard installation for the amd64 architecture, including all standard packages and using the default kernel, takes up 822MB of disk space. A minimal base installation, without the “Basic Ubuntu server” task selected, will take 506MB. Important: In both cases this is the actual disk space used after the installation is finished and any temporary files deleted. It also does not take into account overhead used by the file system, for example for journal files. This means that significantly more disk space is needed both during the installation and for normal system use. The following table lists sizes reported by aptitude for the tasks listed in tasksel. Note that some tasks have overlapping constituents, so the total installed size for two tasks together may be less than the total obtained by adding up the numbers. Note that you will need to add the sizes listed in the table to the size of the standard installation when determining the size of partitions. Most of the size listed as “Installed size” will end up in /usr and in /lib ; the size listed as “Download size” is (temporarily) required in /var . If you install in a language other than English, tasksel may automatically install a localization task , if one is available for your language. Space requirements differ per language; you should allow up to 350MB in total for download and installation. 1. Serial mice usually have a 9-hole D-shaped connector; bus mice have an 8-pin round connector, not to be confused with the 6-pin round connector of a PS/2 mouse or the 4-pin round connector of an ADB mouse. 110 Task Installed size (MB) Download size (MB) Space needed to install (MB) Web server 31 7 38 Print server 234 73 307 Module Description psmouse PS/2 mice (should be autodetected) usbhid USB mice (should be autodetected) sermouse Most serial mice logibm Bus mouse connected to Logitech adapter card inport Bus mouse connected to ATI or Microsoft InPort card D.2.
