+ | 26/03/2019 03:17:13 other clients: | ||
+ | 26/03/2019 03:17:13 X DAMAGE available on display, using it for polling hints. | ||
+ | 26/03/2019 03:17:13 To disable this behavior use: '-noxdamage' | ||
+ | 26/03/2019 03:17:13 | ||
+ | 26/03/2019 03:17:13 Most compositing window managers like 'compiz' or 'beryl' | ||
+ | 26/03/2019 03:17:13 cause X DAMAGE to fail, and so you may not see any screen | ||
+ | 26/03/2019 03:17:13 updates via VNC. Either disable 'compiz' (recommended) or | ||
+ | 26/03/2019 03:17:13 supply the x11vnc '-noxdamage' command line option. | ||
+ | 26/03/2019 03:17:13 | ||
+ | 26/03/2019 03:17:13 Wireframing: -wireframe mode is in effect for window moves. | ||
+ | 26/03/2019 03:17:13 If this yields undesired behavior (poor response, painting | ||
+ | 26/03/2019 03:17:13 errors, etc) it may be disabled: | ||
+ | 26/03/2019 03:17:13 - use '-nowf' to disable wireframing completely. | ||
+ | 26/03/2019 03:17:13 - use '-nowcr' to disable the Copy Rectangle after the | ||
+ | 26/03/2019 03:17:13 moved window is released in the new position. | ||
+ | 26/03/2019 03:17:13 Also see the -help entry for tuning parameters. | ||
+ | 26/03/2019 03:17:13 You can press 3 Alt_L's (Left "Alt" key) in a row to | ||
+ | 26/03/2019 03:17:13 repaint the screen, also see the -fixscreen option for | ||
+ | 26/03/2019 03:17:13 periodic repaints. | ||
+ | 26/03/2019 03:17:13 | ||
+ | 26/03/2019 03:17:13 XFIXES available on display, resetting cursor mode | ||
+ | 26/03/2019 03:17:13 to: '-cursor most'. | ||
+ | 26/03/2019 03:17:13 to disable this behavior use: '-cursor arrow' | ||
+ | 26/03/2019 03:17:13 or '-noxfixes'. | ||
+ | 26/03/2019 03:17:13 using XFIXES for cursor drawing. | ||
+ | 26/03/2019 03:17:13 GrabServer control via XTEST. | ||
+ | 26/03/2019 03:17:13 | ||
+ | 26/03/2019 03:17:13 Scroll Detection: -scrollcopyrect mode is in effect to | ||
+ | 26/03/2019 03:17:13 use RECORD extension to try to detect scrolling windows | ||
+ | 26/03/2019 03:17:13 (induced by either user keystroke or mouse input). | ||
+ | 26/03/2019 03:17:13 If this yields undesired behavior (poor response, painting | ||
+ | 26/03/2019 03:17:13 errors, etc) it may be disabled via: '-noscr' | ||
+ | 26/03/2019 03:17:13 Also see the -help entry for tuning parameters. | ||
+ | 26/03/2019 03:17:13 You can press 3 Alt_L's (Left "Alt" key) in a row to | ||
+ | 26/03/2019 03:17:13 repaint the screen, also see the -fixscreen option for | ||
+ | 26/03/2019 03:17:13 periodic repaints. | ||
+ | 26/03/2019 03:17:13 | ||
+ | 26/03/2019 03:17:13 XKEYBOARD: number of keysyms per keycode 7 is greater | ||
+ | 26/03/2019 03:17:13 than 4 and 51 keysyms are mapped above 4. | ||
+ | 26/03/2019 03:17:13 Automatically switching to -xkb mode. | ||
+ | 26/03/2019 03:17:13 If this makes the key mapping worse you can | ||
+ | 26/03/2019 03:17:13 disable it with the "-noxkb" option. | ||
+ | 26/03/2019 03:17:13 Also, remember "-remap DEAD" for accenting characters. | ||

+ | Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet? | ||
+ | |||
+ | The scheme stores pixel data offscreen on the VNC viewer side for faster | ||
+ | retrieval. It should work with any VNC viewer. Try it by running: | ||
+ | |||
+ | x11vnc -ncache 10 ... | ||
+ | |||
+ | One can also add -ncache_cr for smooth 'copyrect' window motion. | ||
