حل مشکل در "No -display or DISPLAY." برای ایمیج کوبین

[dostajn]

باسلام
امروز بعد از مدتها برگشتم سر برد کوبی برد و خواستم با کوبین کار کنم.
متاسفانه اون موقع نتونستم vnc رو روی این برد راه بندازم، اما الان برای یکاری دوباره اومدم سراغ این برد و با دادین یه تیکه از آموزش تصویری آقای چنگالی بفکر افتادم که از نو شروع کنم به راه اندازی اون،‌ اما دوباره همون ارور سابق رو داد و متوجه شدم خود آقای چنگالی هم به همین مشکل می خورن و بدون اراپه راه حلی ازش رد میشن!! !(خونه دوستم یه بار دیدم اما بدلیل قطع برق نتونستم دوباره یه نکاه بندازم و درست مراحل آقای چنگالی رو یادم نمی یاد)
لذا خودم شروع کردم به سرچ تو اینترنت و عاقبت مشکل رو پیدا کردم
بعد از نصب x11vnc توسط فرمان زیر:


sudo apt-get install x11vnc
طبق دستور العمل که تو اینترنت دیدم باید یه پسورد برای vnc ساخت با دستور:


x11vnc -storepasswd

اما با خطای زیر روبرو میشدم:


cubie@Cubian:~$ x11vnc -storeasswd

27/07/2014 23:42:35 To disable this behavior use: '-noxdamage'
27/07/2014 23:42:35
27/07/2014 23:42:35 Most compositing window managers like 'compiz' or 'beryl'
27/07/2014 23:42:35 cause X DAMAGE to fail, and so you may not see any screen
27/07/2014 23:42:35 updates via VNC. Either disable 'compiz' (recommended) or
27/07/2014 23:42:35 supply the x11vnc '-noxdamage' command line option.
27/07/2014 23:42:35
27/07/2014 23:42:35 Wireframing: -wireframe mode is in effect for window moves.
27/07/2014 23:42:35 If this yields undesired behavior (poor response, painting
27/07/2014 23:42:35 errors, etc) it may be disabled:
27/07/2014 23:42:35 - use '-nowf' to disable wireframing completely.
27/07/2014 23:42:35 - use '-nowcr' to disable the Copy Rectangle after the
27/07/2014 23:42:35 moved window is released in the new position.
27/07/2014 23:42:35 Also see the -help entry for tuning parameters.
27/07/2014 23:42:35 You can press 3 Alt_L's (Left "Alt" key) in a row to

27/07/2014 23:42:35 periodic repaints.

27/07/2014 23:42:35 or '-noxfixes'.
27/07/2014 23:42:35 using XFIXES for cursor drawing.

27/07/2014 23:42:35 Scroll Detection: -scrollcopyrect mode is in effect to
27/07/2014 23:42:35 use RECORD extension to try to detect scrolling windows
27/07/2014 23:42:35 (induced by either user keystroke or mouse input).

27/07/2014 23:42:35 If this makes the key mapping worse you can
27/07/2014 23:42:35 disable it with the "-noxkb" option.
27/07/2014 23:42:35 Also, remember "-remap DEAD" for accenting characters.

مشکل ظاهرا طبق چیزی که اینجا (You can see links before reply)گفته به علت عدم لاگین شدن رخ میده!یعنی قبل از اینکه به سرور vnc بزنید باید اول لاگین کنید نمی دونم ssh چیکاره ست...
و اگر خواستین در مورد روشهای اتصال به سرور X بدونین اینجا (You can see links before reply) کمک تون میکنه.
البته من خودمم زیاد سر در نیاوردم اما د رکل تونستم مشکلم رو به راحتی برطرف کنم،‌گفتم بگم شاید بدرد یکی بخوره :)


sudo x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -storepasswd


بعدشم:


sudo x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -usepw
