Automatically starting X with GDM in Backtrack

ကြ်န္ေတာ္တုိ႔ Backtrack5 မွာ Boot တက္လုိက္ရင္ အျခား Windows, Ubuntu တုိ႔လုိ username, password ရုိက္ေပးရမယ့္ Login Screen ကုိတန္းမေရာက္ဘူးဗ်။ အဲဒီအစား Command line ကေန usernae, password ကုိရုိက္ေပးရတယ္။ ျပီးတာေတာင္ startx လုိ႔ရုိက္ေပးရေသးတယ္။ ကြ်န္ေတာ္အစကမသိလုိ႔ အင္စေတာ့လုပ္ျပီးတာေတာင္ ဘယ္နားကေနဝင္ရမွန္းမသိလုိ႔ ေတာ္ေတာ္တုိင္ပတ္ဖူးတယ္။ ေလထွာ။ :D အခု Tool ေလးကုိအသုံးျပဳျပီး သူမ်ား OS ေတြလုိ password ရုိက္ရမယ့္ေနရာမွာ လူလုိသူလုိျဖစ္ေအာင္ ေျပာင္းၾကည့္မယ္ဗ်ာ။ :P

အရင္ဆုံး Terminal ကေန apt-install gdm လုိ႔ရုိက္လုိက္ပါ။ ဒါဆုိ သူ႕ဟာသူဆက္လုပ္သြားပါလိမ့္မယ္။ သိပ္မၾကာပါဘူး။ Done ဆုိျပီးေပၚလာရင္ ေတာ္ေတာ္ဟုတ္ေနပါျပီ။ 

အုိခီ ျပီးရင္ အလုပ္ျဖစ္မျဖစ္ Terminal မွာ gdm ဆုိျပီးရုိက္ၾကည့္လုိက္ပါ။ ေအာင္ျမင္တယ္ဆုိရင္ Logon Screen ကုိျပေပးပါလိမ့္မယ္။ ေနာက္ Terminal ကေန nano /etc/init/gdm.conf ဆုိျပီးသြားရင္လည္းရတယ္။ ဒါမွမဟုတ္ Computer>File System>etc>init>gdm.conf ဆီကုိသြားျပီး အဲဒီ gdm.conf ဖုိင္ကုိဖြင့္လုိက္ပါ။ ဒါဆုိရင္ အထဲမွာ config ဖုိင္ကုိေတြ႔ရပါမယ္။ မူလအတုိင္းဆုိရင္ ေအာက္ကအတုိင္းျဖစ္ပါလိမ့္မယ္။
