Assunto: problemas de exibição de caracteres nos Terminais Virtuais F1-F6
 
 
- ------------------------------
- ------------------------------
 
Então, o problema é que alguns caracteres não estavam sendo exibidos
corretamente nos seis Terminais Virtuais (F1-F6).
 
Dá uma olhada em alguns exemplos abaixo:
 
 
saída do comando <cp -v teste1.txt teste5.txt>:
 
“teste1.txt” -> “teste5.txt”
 
 
saída do comando <cp -v screenlog.0 ~/>:
“screenlog.0” -> “/home/jamenson/screenlog.0”
 
 
saída do comando <mv -v teste* ~/>:
“teste1.txt” -> “/home/jamenson/teste1.txt”
“teste2.txt” -> “/home/jamenson/teste2.txt”
“teste3.txt” -> “/home/jamenson/teste3.txt”
“teste4.txt” -> “/home/jamenson/teste4.txt”
“teste5.txt” -> “/home/jamenson/teste5.txt”
 
 
saída do comando <rm -v ~/teste*>:
removido “/home/jamenson/teste1.txt”
removido “/home/jamenson/teste2.txt”
removido “/home/jamenson/teste3.txt”
removido “/home/jamenson/teste4.txt”
removido “/home/jamenson/teste5.txt”
 
 
- ------------------------------
- ------------------------------
 
 
Aqui nos meus seis Terminais Virtuais (F1-F6), ao invés de um " (código ASCII 034),
o sistema está gerando um carácter þ (código ASCII 254).   Eu também constatei que
nos Terminais Virtuais Emulados no Debian GNU/Linux 8 (Jessy) - dentro do Servidor X -
o problema não aparece.
 
Eu até comparei essa mesma situação em um sistema GNU/Linux From Scratch 7.6-systemd,
sabido que o pessoal do Debian GNU/Linux 8 (Jessy) recentemente migrou do esquema de
inicialização SysV para o systemd, de forma que eu entendo que a comparação é
relevante.
 
 
- ------------------------------
- ------------------------------
 
 
 
Adicionalmente, o carácter ã não estava sendo exibido nos Terminais Virtuais (F1-F6).
 
 
 
- ------------------------------
- ------------------------------
 
 
Para resolver tais problemas, a configuração mencionada é obrigatória, pelo menos
por enquanto, especialmente esta:
 
# CONFIG_DRM_I915 is not set
# CONFIG_DRM_I915_KMS is not set
# CONFIG_DRM_I915_FBDEV is not set
# CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT is not set
 
 
- ------------------------------
- ------------------------------
 
 
No GNU/Debian 8 (Jessy), a configuração original é esta:
 
 
CONFIG_DRM_NOUVEAU=m
CONFIG_NOUVEAU_DEBUG=5
CONFIG_NOUVEAU_DEBUG_DEFAULT=3
CONFIG_DRM_NOUVEAU_BACKLIGHT=y
 
CONFIG_DRM_I915=m
CONFIG_DRM_I915_KMS=y
CONFIG_DRM_I915_FBDEV=y
# CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT is not set
 
 
Tal configuração não funciona corretamente.   Mesmo que se pense que o módulo correto
será carregado pelo kernel, ainda assim, essa configuração não funciona corretamente,
pelo menos por enquanto.
 
 
- ------------------------------
- ------------------------------
 
 
 
Espero ter esclarecido o objetivo deste tópico.
 
 
Felicidades.

Qual o problema? Estás sem saída de vídeo? Estás sem 3d? Resolução baixa?
