\"\"<\/a>O kernel Linux 3.2.0 do Ubuntu 12.04 reconhece o tablet<\/em> Genius WizardPen 4×3 sem necessidade de instalar nada. \u00c9 s\u00f3 plugar e usar. Esta \u00e9 a boa not\u00edcia. O tablet<\/em> \u00e9 reconhecido e usado pelo driver evdev<\/strong> como um input device, tal qual teclado, mouse<\/em>, touchpad<\/em>.

O m\u00e1ximo de calibra\u00e7\u00e3o que se consegue \u00e9 mudar a \u00e1rea \u00fatil “x y” do pad. Para diminuir a \u00e1rea e deixar seu uso mais ergon\u00f4mico, coloquei este c\u00f3digo no arquivo \/etc\/X11\/xorg.conf, depois de fazer um backup do original:<\/p>\n

Driver para vers\u00f5es anteriores do Ubuntu<\/h3>\n
O driver<\/em> GNU\/Linux Ubuntu 10.04 Lucid Lynx para o tablet Genius WizardPen 4×3<\/strong> (identificado pelo Linux como “UC-LOGIC Tablet WP4030U<\/strong>“) est\u00e1 em https:\/\/launchpad.net\/wizardpen. \u00c9 f\u00e1cil instal\u00e1-lo atrav\u00e9s do Synaptic. Primeiro, atualizei os reposit\u00f3rios com o PPA do driver<\/em>.<\/p>\n
Adicionando o PPA<\/h3>\n
Fui a Sistema > Administra\u00e7\u00e3o > Canais de Software > Outro Software<\/strong> e cliquei Adicionar<\/strong>. Adicionei esta linha:<\/p>\n
ppa:doctormo\/xorg-wizardpen<\/pre>\n
Depois de clicar em “Adicionar canal” e “Fechar”, recarreguei as fontes de software. Agora, usei o Synaptic (Sistema > Administra\u00e7\u00e3o > Gerenciador de pacotes Synaptic<\/strong>) para instalar o driver. Para achar o driver, escrevi “wizardpen<\/strong>”\u00a0 no campo “Pesquisa R\u00e1pida”. Marquei-o e instalei-o. Encerrei a se\u00e7\u00e3o de usu\u00e1rio\u00a0 (login) e entrei novamente para fazer o ambiente de janelas Xorg carregar o m\u00f3dulo.<\/p>\n
Mas precisei calibrar o WizardPen, porque estava com a press\u00e3o (eixo Z) muito sens\u00edvel. Era f\u00e1cil deslocar ou clicar em algo por engano. Descobri alguns par\u00e2metros de configura\u00e7\u00e3o (valores X e Y do tablet<\/em>)\u00a0 com o seguinte comando, no terminal:<\/p>\n
sudo wizardpen-calibrate \/dev\/input\/event4<\/pre>\n
Em vez de \/dev\/input\/event4, o tablet<\/em> pode estar em outro lugar. Varia conforme a porta USB ou o n\u00famero de dispositivos, talvez. Descobri\u00a0 procurando (CTRL+F) “4030” nos logs do sistema, pelo programa Visualizador de Arquivos de Log (Sistema > Administra\u00e7\u00e3o<\/strong>). Mas o comando wizardpen-calibrate s\u00f3 gera os par\u00e2metros necess\u00e1rios para se definir a \u00e1rea \u00fatil <\/strong>do tablet<\/em>. N\u00e3o configura nada e n\u00e3o gera os par\u00e2metros para a sensibilidade \u00e0 press\u00e3o da caneta, que era o meu problema.<\/p>\n
Esse par\u00e2metros deveriam ser\u00a0 colocado no arquivo de configura\u00e7\u00e3o do Xorg (\/etc\/X11\/xorg.conf), conforme o manual do Wizardpen. Mas isto n\u00e3o funcionou, talvez porque o Xorg agora usa o udev como configurador. O log do Xorg reportava:<\/p>\n

Mas isto tamb\u00e9m n\u00e3o funcionou, embora o log do sistema udev tenha reportado que as vari\u00e1veis de ambiente foram setadas corretamente. Deve ser problema do Xorg.<\/p>\n
Mas tamb\u00e9m descobri os v\u00e1rios arquivos de configura\u00e7\u00e3o, entre os arquivos do driver (vendo os arquivos do pacote pelo Synaptic), que podem variar conforme o sistema (para o udev ou para o HAL). J\u00e1 que o Ubuntu n\u00e3o usa mais o HAL, ignorei seus arquivos de configura\u00e7\u00e3o e resolvi mudar o arquivo \/usr\/lib\/X11\/xorg.conf.d\/70-wizardpen.conf<\/strong>, (Ubuntu Lucid 10.04) ou \/usr\/share\/X11\/xorg.conf.d\/70-wizardpen.conf<\/strong> (Ubuntu Maverick 10.10), do sistema udev, conforme assinalado abaixo. TopZ \u00e9 a press\u00e3o m\u00ednima — no meu caso, ficou boa com 100 —\u00a0 e BottomZ \u00e9 a press\u00e3o m\u00e1xima da caneta — deve ser 511.<\/p>\n

\u00c9 fora dos padr\u00f5es configurar as coisas fora do diret\u00f3rio \/etc, mas funcionou. Agora j\u00e1 posso ajustar os diversos par\u00e2metros do tablet. Para descobrir estes par\u00e2metros, li o manual do m\u00f3dulo WizardPen com o seguinte comando:<\/p>\n
