Ubuntu-fr

perso je le lance avec:
sudo minidlnad -f /etc/minidlna.conf -R
A mon avis tu devrais essayer le -R
-R
    Forces a full rescan of the media files.
et
-f config_file
    Specify the location of the configuration file. Uses /etc/minidlna.conf by default.

Le -R comme je te l'ai dit plus.
Enfin je pense

Lance gufw
Clique sur + pour ajouter une règle
Tu mets le nom de ta règle : minidlna par exemple
Tu choisis: autoriser
Protocole : les 2 udp et tcp
puis tu mets le numéro du port 49200 (49220 par défaut cf le fichier de /etc/minidlna.conf, j'utilise 8200 et je sais plus pourquoi)
Je viens de le mettre à jour y a 5 min. Je suis au point si tu as des questions.

1/ quel est ta carte graphique ?
2/ c'est quoi LMMS ?
3/ Pourquoi LMMS ne marcherais pas avec la version 1.4 de wine ? (A tester)
4/ c'est très rapide de tester la version 1.4 de wine.

1/ Perso. j'émule avec windows xp
2/ Je ne vois pas pourquoi ça ne marche pas. Faut voir ce que dit le log qd tu lance le jeu
3/ Ci-dessous la configuration des registres que j'utilise avec wine (essaye de mettre pareil):

[HKEY_CURRENT_USER\Software\Wine\Direct3D]
"AllowMultiSampling"="enabled"
"OffscreenRenderingMode"="fbo"
"PixelShaderMode"="enabled"
"UseGLSL"="enabled"
"VertexShaderMode"="hardware"
"VideoMemorySize"="1024"

pour lancer steam dans un terminal:
- cd "emplacement du dossier de steam"
- puis wine steam.exe

tu vas dans ton dossier de ton compte. Tu fait crt + h (pour voir les fichiers cachés)
steam doit être dans le dossier /.wine/drive_c/Program Files/steam

Une petite recherche sur internet (wine No OpenGL extensions found)
Il semble que ton problème proviennent de paquet manquant lié à l'opengl et le 32 bit.
As-tu le paquet suivant installé : ia32-libs ?
A installer si non

3/ Pour les options de lancement, tu as enlevé -windowed (lancement en mode fenetre) combiné à -noborder ça te permets de faire du alt+tab sans aucun problème puis ajouter la résolution à utiliser avec -width 1920 -height 1200
4/ J'avais aussi oublié. Dans les propriétés de steam dans l'onglet ingame, il faut déactiver le steam community in-game
5/ La configuration du jeu peut être géré grâce au fichier "autoexec.cfg"situé dans :
Steam/SteamApps/ton_de_compte_steam_/team fortress 2/tf/cfg
Une recherche sur internet te permettra de trouver plein de fichiers modifiés suivant différents objectifs (perf. ou meilleur graphisme)
Ci-dessous le contenu de mon ficher qui me va bien:

// Unexplained crashes? Try changing mat_queue_mode to `-1'.

// Chris' highframes config, designed to get you a large performance boost
// v2.004 | 11 October 2011 | fakkelbrigade.eu/chris/configs/

// Problems or questions? Contact me at #christf2 on QuakeNet.

// FPS cap
// ----------------------------------------------------------------------------
// The primary benefit of an FPS cap is to make the FPS more stable, other than
// that, it doesn't do a lot. A moderate, consistent framerate is much more
// desirable than a variable but sometimes high framerate. A common
// misconception is that if any more frames are generated than your monitor can
// display, they are useless. This is wrong -- frames are used for much more
// than mere display, and affect the way the game feels well past your
// refresh rate.
//
// This FPS cap should *always* be set to a value higher than `cl_cmdrate' in
// any case, or the discrepancy between clientside frame generation and frames
// to be sent to the server will no doubt cause you many a headache, especially
// when it comes down to hit registration. Other than that, I recommend
// for everyone to use the value `132' (2*66), as long as you can generally
// keep that value stable without regular drops.
// ----------------------------------------------------------------------------

// Whilst net settings perhaps aren't an integral part of an FPS config, they
// are a fact of life in competitive TF2, and as such, they are included here.
//
// A common question I am asked -- what defines whether a good connection is
// good or bad? Mostly personal preference. If you're not willing to make the
// choice, try both and see which is better for you.
//
// Generally, meeting both of the following conditions would classify it as a
// good connection:
//
// - Ping of <80 to the average server you join
// - Generally no/negligible choke/loss (can be checked with `net_graph')
//
// There's some pretty good documentation on this here:
// http://developer.valvesoftware.com/wiki … Networking

1) Effectivement, après vérif., je n'ai que le filtrage anisotropique de dégrisé. Question con, tu lance le jeux à la résolution native de ton écran ? (option de lancement ex :-width 1920 -height 1200)

2) Pas d'idée

3) Normalement c'est mieux

Pour moi en nvidia 560GTX, TF2 fonctionne bien hors mis:
- random crash (mais je peux jouer longtemps)
- problème d'affichage des textes sur certains serveurs (ex: nom des joueurs et chat) / la plus part des caractères sont manquants mais cela n’empêche pas de jouer
