From OLPC

[edit] To Do

• yum inst. linux-wacom .o0(please, please, please work?)
• Install olpc.icc, then figure out what's the color correction system
• Notes to document:
  1. there's a menu-related panel thingie package that'll prevent menubars for appearing at all makes menubars act in ways not entirely expected (fixed in later versions).
  2. Desktop settings seem to reset after a logout/restart/shutdown. Understandable (consistency), but an annoyance. A sudo nano should fix that
• VNC and/or SSH
  • yum install x11vnc (libvncserver, lzo-minilzo, xorg-x11-server-Xvrfb)
  • /etc/avahi/services to b'cast/advertise
  • still needs vncpasswding

[edit] Alt. OSs

• FreeDOS:\isolinux\data\memdisk identified as "Linux kernel x86 boot executable bzImage" but OFW claims "Invalid Opcode" - known not to work, but worth trying anyway. Doesn't work ;-(
• Extremely tempted to install RHEL6 (Sci Linux, actually): LiveCD-to-USB, then install to SD card?? OpenFirmware crashes with "General Exception Fault" and "General Protection Failure" (depending on the phase of the moon). Looks like these distros are expecting BIOS/EFI despite purporting XO support (or perhaps they're having conniptions with XO anti-theft?)

[edit] Done

• yum install "gedit*plugin*" installs texlive as dep (∑75MB).
  • Could use TeXLive 2010 install (from ISO).

[edit] VM

512MB is a must for any GNOME-work.

[edit] fonts

• liberation-{sans,serif,mono}, sil-gentium-fonts
• FixedSys Excelcior or PR fonts are ok, but there just isn't a "must-have" monospaced font that's legible, appealing, and has character (pun not intended).
  sudo cp whatever to /usr/share/fonts
  108 DPI for GNOME is just about right 133.333333 dpi, actually - Thanks to AuntiMame for providing the width and height of the XO's screen (among other troves), and to whoever it was who made ◊1 produce screenshots. Hence:
• 1200px ÷ 9 inches = 133.333333 px per inch
• 900px ÷ 6³/₄ inches = 133.333333 px per inch
  (just making sure)
• 133.333333 px per inch ≈ 5.249343 dots per mm (for our metric friends)

[edit] Goog Chrome

Ugh, but it's leaner than FiFox. It also suffers from DPI-ditziness (why, oh, why?)

• requires LSB≥3.2
  1. yum install redhat-lsb
     gives that @#$%ing "out of space" error (not with a 16GB SD you aren't!!!!)
  2. console: -> /sbin/init 3 ... yum install redhat-lsb
     ditto >_<
  3. #ed "/var" mounts; restart
  4. Gnome: yum install redhat-lsb
     Works! Dependencies: m4 make patch pax
• Grab Goog's rpm (where's the SRPM you "let's not be evil" b*****ds?!)
• rpm -ivh g...rpm OK
  As sluggish as FiFox, as alien as M$Office 12

Warning: Geo.Loc., D/L Loc., privacy settings, lame "oops" messages when there's a Flashy page (y'shouldda asked, Goo... y'shouldda asked first.)

[edit] Gnome Screenshot

• yum install gnome-utils (deps. libgtop2)
  I wonder if I can change the keystroke for snapshotting to "frame" (and alt-tab to the key next to it?)Yep.

[edit] Office

• Very tricky installation (read: plethora of annoying "oops" boxes from wine) from command line, but works. Apps' bootsplashes will obscure a dialog box asking for first-time user ID info, so it looked like the apps were hanging. DPI issue resolved (use Wine Config to set DPI)

[edit] Kile

Note: Fuhgeddaboudit - Resource hog.

• yum shows 82MB in deps, but that doesn't count deps installed from gedit's latex plugin. yum doesn't install KDVI, which Kile will complain about during a systems check.
• Still suffers from DPI ditziness, but it's not as bad as it was with 10.1.2.

[edit] Android SDK

In the end... no: The SDK is wonky using the "open" Java, and running the "official" Java is like wading through tar.

[edit] Doing

[edit] yum

If you run it from command line as user olpc, it'll trigger the "out of space" error - even if you su to root afterwards. Seems to be a failsafe, acts like a nasty bug.
