Windows or Linux has a long way to go

These are just my thoughts on what I feel subjectively.

I feel Windows or Linux has a long long way to go, nay not even touch the power or bring the amount of satisfaction a gaming console offers.

After playing uncharted 2 in PS3 , I feel how much optimized and how efficient the code has been written. Shame, still windows or linux fails to get past i386 stuff with all arguments i386 is same as i686,  and saying there is no gain in optimization it still works no wonder and feels like 10 year old and sloooow even after having a quad core or a core 2 duo


A PS3 is a generation ahead of conventional PC's not just in hardware. Take any gaming console and I bet after using them, you won't feel your PC is even able to emulate the same game after 5 years. The reason is simple, your GPU (Graphics card) is not being utilized, quad core or its instruction set is not being utilized by your i386 OS unlike how a game on console does

A PS3 has just 256 MB RAM and another 256 MB RAM for graphics and it is able to process OS, process your 60 GB blue ray movie, process your GAME all along with running a hypervisor which is a virtual machine.

Take windows, a 1 GB is not enough for your OS!! What a shame.
Not just that, your PC will hang while copying big file, though you have 4 GB RAM if you run under linux.What a shame.

True PS3  has a cell broadband engine which is a supercomputing chip, but even a core i7 is good one with its 8 cores (physical 4 cores) but it is no match for a PS3 or XBOX or even a PS2 (go play god of war 2 in PS2 before attacking me). Not even a 1 GB graphics card be able to play the same amount of graphics in a PC, real reason, drivers and code for a console is super optimized whereas for a PC it is not, it is still old i386


Prove me wrong, don't just show crysis game, wan't every app to be so superb like how a game immerses you with gameplay. Don't just give me a script

I would love to see a super optimized OS run on a core 2, able to do wonders like a gaming console. Just dreaming


Comment from my friend: It is true that gaming consoles are remarkable in computing, but they are not like general purpose OS, where they allow multiple process to run simultaneously and gaming consoles are uniprocess and hence the difference.

I agree with my friend's comment, but I still think, conventional OS is lacking speed due to poor optimization. Does it mean, that since conventional OS supports multi tasking, it can't do high performance computing like a dedicated console? I dont know (Do you feel conventional OS like how an Aeroplane is used like a street CAR which always runs on road and never takes off?)

5 tips to make ubuntu lucid beta really lucid

1. Disable nouveau driver from loading
while booting into ubuntu press tab and add the following text to disable nouveau

 nouveau.blacklist=true

This will disable the nouveau driver from getting loaded. nouveau driver when booting into ubuntu corrupts display and the session becomes unusable with a hang. This option will force ubuntu to avoid loading buggy nouveau driver

2. Minimize, Maximize and Close buttons on right of titlebar

To move the titlebar icons  minimize, maximize and close buttons to right

gconftool-2 --set /apps/metacity/general/button_layout --type string :minimize,maximize,close   



If you want to do it graphically, rather than command line, launch gconf-editor (from quick launch by pressing Alt +F2) and search for metacity then edit the textbox button_layout under general to have value :minimize,maximize,close

3. Control Alt Backspace to kill X server

To enable ctrl + alt + backspace to restart X server, goto System --> Preferences --> Keyboard --> Layouts --> Options --> Key sequence to kill the X server and tick the checkbox

Control + Alt + Backspace

After this pressing Control + Alt + Backspace will restart X server

4. Enable icons in menus

To enable icons in menus,

gconftool-2 --set /desktop/gnome/interface/menus_have_icons --type boolean True

See the icons in the context menu in desktop below after enabling menus


5. Disable update notifier from popping on your face

gconftool-2 --set /apps/update-notifier/auto_launch --type boolean False







Here ends the tips, the following are some general screenshots under Ubuntu Lucid beta after customizations from above tips

Screenshot of nvidia-settings after enabling nvidia from Hardware Drivers and pressing control + alt + backspace to restart X server (to enable control + alt + backspace to restart X server, see 3rd tip above)



After restarting X, the user name in live session is ubuntu and password is blank password

Enjoy Ubuntu Lucid though it is in beta now
