Carbon X1 a RHEL 7.5 = je sanca 1:1 ze po tom co zaklapnem vieko na laptope, ze sa uz neprebudi, takze ho musim natvrdo vypnut a znovu zapnut. Nejde prepnut ani do do textovych konzol, je to uplne mrtve.

0000010100063540027994150852344708524472

vypni hw acceleration pre modesetting driver..

vytvor file /etc/X11/xorg.conf.d/10-modesetting.conf

Section "Device"
Identifier "Intel Graphics"
Driver "modesetting"
Option "AccelMethod" "none"
EndSection

edit:
testoval sa este novy kernel, netusim v ako stave je toto, RH je pomaly jak slimak .. ked tak skus kernel z http://elrepo.org/tiki/Download

a mam taky pocit, ze to nie je dobre...

napriklad tu :

ale moc sa v tom nevyznam... vie mi niekto poradit?

vdaka moc

... keď napneš strunu moc - praskne, keď ju napneš málo - nebude hrať ...

0000010100063540027994150807114608071780

vidis nejaky error ked ti to nebootuje?
skus nabootovat jeden z tych kernelov tak, ze das prec 'LANG=en_US.UTF-8' z kernel riadku

000001010006354002799415080711460807178008074302

vymazal som ale nepomohlo.
ziadny error nevidim a neviem sa nejako dostat k boot logu, pretoze vzdy vidim len ten posledny, teda ten ktory je na starom kernel a teda nabootuje, ale ine logy nejako neviem najst... je moznost?

zdochne mi to na tejto obrazovke

... keď napneš strunu moc - praskne, keď ju napneš málo - nebude hrať ...

00000101000635400279941508071146080717800807430208102592

mrkni, ci nemas /var/log/kernel
inak skus syslogd nastavit, aby logoval kernel messages (pogoogli - #klogd, #sysklogd, #syslogd).
Inac neblika ti caps lock? ze ci to nie je rovno kernel panic

0000010100063540027994150807114608071780080743020810259208107498

no, kernel-3.10.0-327.10.1.el7.x86_64 mi nabootuje v pohode na prvy krat bez chyby, takze to uz asi opravili...

vdaka za tip, pokusim sa nieco vyhladat...
co sa CAPS tyka, nevsimol som si, ze by blikal...

skusal som este hladat na nete a skusal som aj nejake rady co som nasiel, ale nic nepomohlo... mozno ten log, vdaka :)

... keď napneš strunu moc - praskne, keď ju napneš málo - nebude hrať ...

00000101000635400279941507726402

Presiel som na CentOS 7.
Dal som minimal desktop.
Spustanie mi trva celkom dlho, moze to byt sposobene kryptovanim disku?
(oproti vypinaniu, ktore trva asi 3 sekundy)

0000010100063540027994150772640207728302

to by som nepovedal (krypt)
pozri sa kde ti to pri boote brzdi ..

mysql_connect("localhost",...) - funguje
mysql_connect("domena.sk",...) - nefunguje

nemam poruke rh6 ani php ale
skus zo shellu connect na tu mysql instanciu
mysql -h localhost -P 3306 (alebo aky port)
mysql -h domena.sk -P 3306
ak sa to pripoji alebo odmietne kvoli chybajucemu menu/heslu tak s velkou pravdepodobnostou nemas vyriesene granty
tj v mysql
show grants for 'user'@'localhost'
show grants for 'user'@'domena.sk'
pretoze to su dvaja rozlicni useri
mysql -h localhost -P 3306 -u username -p
mysql -h domena.sk -P 3306 -u username -p

takze sa snazis pripojit na mysql na stroji 62.197.207.159

a to nie je ten isty ako tvoj localhost/192.168.0.10
