A tecla Shift não funciona com teclas F1, F2 etc. no gnome2. Qual seria a razão?

Question

Eu tenho uma sessão vnc com o desktop gnome2.

Seguem-se alguns exemplos em que o pressionamento múltiplo de teclas funciona como esperado e os dois últimos exemplos têm resultados inesperados (com F1 & F2 ).

Por favor ajude.

• A tecla Shift é liberada.

Então, mantendo pressionada a tecla Shift e Pressionando F1 , obtemos o seguinte resultado:

• Shift é pressionado e (e a tecla Shift é liberada)
• A tecla F1 é pressionada (e a tecla Shift é pressionada)
• A tecla F1 é liberada e a tecla Shift é liberada

Isso significa que a tecla shift está sendo liberada quando a tecla F é pressionada.

Como evitar isso?

Alt está funcionando bem com as teclas F.

O seguinte é o xmodmap para esse servidor:

xmodmap:  up to 4 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x6d)
mod1        Alt_L (0x40),  Alt_R (0x71),  Meta_L (0x9c)
mod2        Num_Lock (0x4d)
mod3      
mod4        Super_L (0x73),  Super_R (0x74),  Super_L (0x7f),  Hyper_L (0x80)
mod5        Mode_switch (0x8),  ISO_Level3_Shift (0x7c)

O seguinte é o xmodmap de outro servidor onde as teclas Shift + F funcionam:

xmodmap:  up to 2 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock      
control     Control_L (0x25),  Control_R (0x6d)
mod1        Alt_L (0x40),  Alt_R (0x71)
mod2        Num_Lock (0x4d)
mod3      
mod4      
mod5      

Eu tentei remover os últimos 3 modificadores. Mas ainda não funciona. Será necessário reiniciar qualquer serviço para entrar em vigor. Se assim for, não o fiz. No entanto, o reinício do VNC foi completamente redefinido para seus padrões.

Eu também tentei desabilitar as teclas F. Mas não sabe como. E mesmo se eu desabilitar essas ligações de tecla F, os comandos Alt + Chave F não funcionarão direito. Portanto, não devo desabilitar completamente a ligação da tecla F.

Por favor ajude.
